Topic: Can't connect out from local network after changing to dedic

[Rob Bracken]

One of my clients is running SME 5.5. We originally installed it as a dialup server, and installed a 2nd network card to use with an ADSL router.

They've now got an ADSL connection, but they're having trouble connecting out from machines on the local network. Specifically, they need to connect to a specialised server. They can connect from the SME machine, but can't connect from other machines on the local network. It worked before they installed ADSL (and switched to dedicated server).

What do we need to do to allow them to connect out from other machines on the local network?

is the SME server doing dhcp?
if it is, it may be setting itself as the default gateway

check that out

Yes it is, and it probably is setting itself as the default gateway. How will that stop workstations connecting out? What should we set as the default gateway?

More info on the following, please :-

Do you mean, no outbound internet connection at all ? If not, please clarify.

Via VPN ? Or http, ftp, ??? Please be more specific.

The workstations will look to the SME as their route to unknown networks (the Internet). Since the SME is no longer the gateway, the traffic will stop right there.
Maybe you can add a network to the SME of 0.0.0.0 and point it to the new gateway. On second thought I don't think this will work
Or setup static IPs and set the new gateway manually on all of the workstations.
those might work.
If I think of anything else I will let you know.
you might be able to manually edit the config file for dhcp to contain the correct gateway address, however, I do not know what file that would be
maybe /etc/dhcpd.conf or something like that
give it a shot
and remember to make a copy of the original file before you edit it.

good luck

They can browse the web, but can't ftp. ftp from the server works OK.

They have an app. which connects to another server using SSL on port 443 to retrieve information. It's a Windows app.

Thanks, Steve. We'll try that.

Hi Rob,

> installed a 2nd network card to use with an ADSL router.

Most ADSL routers are NAT routers. If your router is setup that way then, you are NATing and NATed connection ?!??

ie.

Internet -> ADSL Router -> SME -> LAN Workstations

See if your ADSL Router can be configured to work like a normal ADSL Modem (instead of a Router). Then let SME handle all routing. Which ADSL router are you using ?

Alernativly, set up the connectiuon to the ADSL router from the SME Server as a seperate subnet.  That works for me.

cheers
