Topic: Grr... No net access, nics are good.

I installed SME on my server, and assigned it all the settings of which I know are correct, as they work on my windows machine, or hardware router when I use them..

My setup is follows..

I have an ip from my isp xxx.xxx.190.237 and its subnet is 255.255.255.248, and its gateway is xxx.xxx.190.254

Then I have 5 ip's to use from my isp behind the above ip address.  Which all are xxx.xxx.188.121 to 125.  They all have .248 subnets.

I setup SME to have external ip of 190.237 and put the gateway in of .254, then made the internal ip 188.121 and set the rest as asked or default.

I can ping all the interfaces from the server, and I can ping the internal (188.121 to 125) ip's. But cannot get outside to the internet.  I can ping the 190.254 gateway, and other ip's who belong to god knows who on 190.xxx but nothing resolves, and cant ping the one external ip I have memorized which is a dns server.


I can pull up the server menu administration through a webpage from the internal lan with no problems...


I am stumped, so please hopefully someone can help....

I can make this stuff work on windows instantly, or using my hardware router, so its a little frustrating for it to not work on this linux package.

Before you suggest bad nics, or wires, keep in mind, that I am using the same cables as when I do it on windows machine or hardware router, and I also tried the installation on two other known working computers...


Many thanks, and I look forward to getting this fantastic looking program to work...

Don't forget that outta the box SME is a nat'd firewall!

Try entering you internal LAN IP info into the Local Networks section in the Server Manager.

Rich,

As Graeme said, SME does NAT internal IP's to a single external IP.   I also have a block of 5 IP's from my isp but I only really need to use 1.  Internally, I allocate private IP's (192.168.X.X) to all my internal servers/workstations.

Another thing to think about, I don't know how you set up your other systems (the WIN box or the hdwe router) but if these are set up to automatically pick up external IP's via PPPoE for example, you will need to set that up on SME.  I have DSL and that's how I set up.  PPPoE provides all the external information needed on start up.  Internally, I have a DHCP server that provides local IP, default gateway IP and DNS (the gateway SME server's internal IP).

If you want your internal workstations to use public IP addresses, I think you'd need something that provides 1 to 1 NAT and by default SME doesn't do this.

Hope this helps...
