Title: Problem accessing internet with server
Post by: k0r54 on January 13, 2007, 01:29:37 AM

Hi,

For some strange reason I seem to be having huge problems my SME Server accessin the internet when it is in server gateway mode.

I have recently got a new router and it happened with the change, but I have checked over and over but the settings seem to be identicle.

When the server is in server mode only it works the internet works fine. but when its server and gateway they do not?

It uses the same network card btw for both modes. The router works perfectly fine for everything else just not that.

Hopefully someone can shed some light into the problem.

Thanks
Adam

You should set your router/modem to bridged mode and disable DHCP and allow sme server gateway to do those functions ie enable DHCP during the console confgure stage (log in as admin).

yeah i have tried that although its a high end router but i cant find the bridge mode on my router. The server is giving out the ip's and because my router (linksys WAG300N is a wirelss too, i have set the dhcp relay to the server).

Any ideas on either why my router is doing it or how to set it to half bribge mode (i have googled it tna).

I also have NAT on because when i turn it off my internet goes down completly to all computers

Thanks

Did you look at page 12 and 15 of your manual ?

Quote from: "Linksys Manual"

Bridge Mode Only
If you are using your Gateway as a bridge, which makes the Gateway act like a stand-alone modem, select
Bridge Mode Only. All NAT and routing settings are disabled in this mode.

Hi william,

Sorry I did not get a manual for it and didn't think about checking it online.

I did notice that and I changed it but when I did my internet would not connected at all. The internet light on the router just went red.

Do you reckon I need anything additional? Or anyother ideas?

Thanks

I'm not a ADSL person more a cable person :)

Do you have to set a username/password in SME (server console) when using bridge mode?

Maybe someone else can answer this.

EDIT: just looked. Login as admin and configure your server. On the External Interface Configuration page select PPPoE.

> Do you reckon I need anything additional?

You do need to enter your ADSL user name and password and type of connection (usually PPPoE) in the sme server console, rather than in the router (as before).

Hi,

Thanks for the fast reply, thing is im in the uk and we actually use pppoa does that make any difference?

Give it ago and see what happens.

If no luck, try RFC 1483 Bridged mode.

Hi k0r54,

Some one will correct me if I am wrong but I don't think SME supports PPPoA :shock:  I have a number of mates in the UK that I have introduced to SME and they (we) have never got PPPoA working on any version of SME  :cry: The only answer we have found is to add the SME server in the routers DMZ so all traffic is forwarded to the server but this would mean you having to have either a different router because you probably use the wireless on your existing router and put your router behind it or put a WAP in place of it. So to recap:
Router
|
|
|
SME Server in Server/Gateway (set to dedicated, DHCP use MAC address, using the first NIC) in DMZ
|
|
|
Switch/Hub - connected to SME's second NIC
|
|
|
WAP (or existing router) and all PC's connected to the hub

This works fine for my mates with PPPoA ADSL The best router we have found is the BT Voyager 220v, simple to set up and works :D It can be found here: http://www.shop.bt.com/invt/car116
Other  bT routers to consider can be found here: http://www.voyager.bt.com/wired_routers/wired_index.htm Of course there are plenty of others from Linksys and Netgear.
Hope this helps.

Regards,
Del

Hi,

Thanks for all your help, unfortunatly all to no avail.

I have tried it all. I think the router is missing the vital drop down of "half-bridge". I have looked for a firmware update but no luck.

Have googled it but no-one with my router is trying to connect to a server apparently  :?

Any more idea's

Thanks

Ok after calling linksys "not so technical support" they said it doesn't support half bridging.

Any other ways around this?

Thanks

In what way does it "not work"?

It uses the same network card btw for both modes.

This doesn't make sense. In server only mode, you use one network card. In server and gateway, it uses two network cards.

Hi,

Firstly when the server is in server mode only the internet works but is server gateway the server does not work at all.

And what I mean by the nics is that the card i use for external interface in server gateway is the card i use for server mode, it elimiates the network as the problem.

Thanks

"The internet" works just fine.  Something about your server is not working right, perhaps because it has been misconfigured. People here will be more likely to help you if you provide more information about exactly how you have configured things, and exactly what works and what does not work.

Thats the problem,

I install sme (fresh install) run through the setup name my pc, i set my local gigabit card up on the 192.168.0.1 and then set internet connection as dedicated, i select static on for the type, i then put my external network card ip in 192.168.0.2 and set the gateway as the router 192.168.0.3 and leave the dns blank.

This does not work.

If i just put it to server only mode, it works fine even if i use my non gigabit card.

I dont configure anything else.

Thanks

That's not surprising. That's an invalid configuration. Try setting your local NIC to 192.168.1.1, and leave the other settings as they are. Your internal and external NICs must be on different IP networks - you have them configured on the same network - 192.168.0.x.

Hi Charlie,

Can you tell me if SME 7.1 supports PPPoA internet connections? I know that here in the US we use PPPoE and that is supported out of the box :D or cable modem, again works first time, every time :D Just curious because I have never been able to get it working with PPPoA  :shock:

Thanks for all your help.

Now working, I was confussed because it used to work like that so not sure why it doesn't now.

Sorry about not puttin up my config :: LESSON LEARNED ::

Set my local to 0.1 external 1.1 and router 1.2.

Another problem which i have posted on linksys is my router offers dhcp relay. It asks for an ip to put it to 1.1 or 0.1 doesn't work.

Any ideas why that might be? I trust dhcp relay is anything that connects to the router (mainly wireless) will get its ip from the server (i.e the address i put in as the relay).

Thanks

Hi k0r54,

Lets recap on your situation, I don't understand how your server can be connected to the router using 2 NIC's and the same IP range :? Either your server should be connected to the router as server/gateway using 1 NIC and the router in bridge mode so it acts like a modem (or put the server in it's DMZ). The server should then be connected to the LAN using it's second NIC and a separate switch/hub and a different IP range with the LAN computers connected to the same switch/hub  :D Or your server should be connected to the router using one NIC in server only mode and all the LAN computers connected the same segment :D If I understand you right you are connecting both server NIC's to the router :cry: if this is right when the server is in server/gateway you have two routers because the server does everything your router does and they could both be acting as the DHCP server for the LAN :shock: Can you just explain exactly what is connected to what, which device is set to DHCP server etc. and maybe we can sort it out :wink:

Del

Hi,

No the router I got is my wireless router aswell.

I have my adsl connecting to my router, which then connects to my external nic on my server. My internal gigabit nic then connects to my hub and to the rest of my network.

When I connect a laptop to the hub on the internal network internet works fine, its great.

It prob doesn't help I have a built in wireless on my router because it puts it onto the external network but anything connected wireless is not gettin an ip address from the server.

The server should be the only dhcp server on the network, the router is only set to relay to the internal ip 0.1

Thanks

If you go back and look at my first post you will see that I have had this problem and the only way to set up is to use a separate router or wireless access point :wink: This will then put the wireless in the LAN segment not the WAN segment. Your router will work fine for the wireless if you put a wired router in place of it and then connect it to the rest of the network and delete the internet settings :D This is an expensive wireless access point but you already have it so why buy something else :D What are your reasons for wanting it in server/gateway mode? Couldn't you use it in server only and forward any ports you need to it from the router? My mates reason was to run sail with a remote extension, but before that he used his in server only and hosted email and web pages by using the port forwarding scenario. Good Luck,

Del

Yeah i kept reading over that post but the dhcp relay was throughing me, I thought my router could do it :(. yeah it is an expensive router but I do have an old router that supports bridging so may use that and configure my wireless as an access point only - just a massive waste of money.

I wanted gateway on the server mainly for ease of use on the port forwarding and email but suppose I can do it in server only mode and leave the forwarding to router, just not what I wanted to do :(

Thanks for all your help though.

Then configure your server for server-gateway mode and put it in front of all your routers.

EG.:

Code: [Select]


Server-----Router------lan
                     \
                       \
                         wlan

This is my configuration.

Have you compared the price of wireless access points and wireless/routers/modems. I think most of the cost is in the wireless part and with yours you get all that funky 'N' stuff.

Post by: k0r54 on January 17, 2007, 01:06:17 PM

Yeah,

I have got it set up now, I had to get my adsl2 modem out and have put my funky wireless router on the internal network as a access point.

Its good just wanted to avoid using a third device lol.

Thanks for all ya help though
