I am having plenty of trouble trying to get my network connecting to the internet via a 2621XM router.
I currently have my network connecting to the internet through an ISA Firewall/Proxy but am wanting to replace this with the 2621XM.
The router has been configured correctly (I assume) from what I have read on the net as wel as from a few colleagues who know more about the ins and outs or this stuff. Access to the internet is still not happening.
I have configured FA0/0 as the outside interface and FA0/1 as the interface. The config for my router is attached. (See file 2621XM_Config - Original.txt)
Once thing that my friends told me was to configure the outside interface with the static IP supplied to me by my ISP.
I know I would only do this if I had my modem in Bridged mode, but as it is currently NAT'ing from my static IP to a 10.x.x.x address, i need not bother with altering it. Should I change it?
(See file 2621XM_Config - Modified.txt)
My internet service is via ADSL.
Neither method has not worked, so I am thinking that there is something missing in each of the configs.
Two questions need answering that I am unsure how to proceed with:
1. the ip domain-name... should this be my public domain name or my internal domain name?
2. the ip name-servers... should these be my ISP name servers or my internal name servers?
My ISA proxy/firewall is setup as a forwarding-only name server and uses my ISP name-servers to forward any requests my internals are unable to resolve. The 2621XM will effectively be doing this from now on.
Does anyone have a working config of a 2621XM that I would be able to use or work from to get my setup working correctly?
Thanking anyone in advance who an help me resolve this.
I should make a few things a bit clearer for future reference.
This config is for a router-on-a-stick setup as I am using 2960 switches (layer 2).
The command 'ip nat outside' is actually in my config on the router. It's just not in the config shown in the attachments. :-D
Re: your 1st point... are you saying that I should remove the 192.168.x.x address? This is only a management address for access to the router. This address will also be the default-gateway for any of my network devices in the 192.168.x.x range.
Can you provide an example of what I should have instead for this interface?
I have done as instructed and can continue to connect via telnet or ping the 192.168.74.254 address. However, I am still unable to ping anything beyond the router. I can ping my DSL modem (10.1.1.1) which then does it's own NAT'ing to my external (ISP) address.
I have included the updated running config for reference.
