Cisco 1601 router config from Polycomm

[scoopseven]

I have a Polycomm router hosting a T1 connection now and I'm trying to connect a Cisco 1601 in place of the Ploycomm with very little success. The Polycomm doesn't really route, I think it acts as more like a bridge. I have a lan block of around 27 IP's(66.87.194.162-165/255.255.255.224) and a WAN IP(66.87.193.2/255.255.255.252). Ideally I'd like to route 4 of my LAN IP's to internal IP's (192.168.0.2-5/255.255.255.0??) and DHCP the rest out to clients. I don't care if the clients are visible via the Internet, they only need internal IP's and access to the Internet.

Furthermore, whenever I try to config the Cisco with the command: network 66.87.194.0 - and I save the config and then go look at it, it says network 66.0.0.0 - why is this happening?

Here's the working Polycomm config and routing table followed by my best attempt at the Cisco config and it's resultant routing table. Any help would be greatly appreciated.

Again, any help is greatly appreciated, as I've been at this for 2 weeks with no success.

I think I know what you want but am not entirely sure. Try this conifg. Rip v1 is a classfull protocol. 66.0.0.0 is a class A subnet so it won't recognize anythig but it. No worries though, you really don't need a routing protocol.

router: 66.87.193.2/255.255.255.252
subnet: 66.87.194.160 255.255.255.224 (usable range 161-191)
static map: 66.87.194.161 - 192.168.0.2
66.87.194.162 - 192.168.0.3
66.87.194.163 - 192.168.0.4
66.87.194.164 - 192.168.0.5
66.87.194.165 - 192.168.0.6
dynamic map:
66.87.194.166-191 - anyone else in 192.168.0.0
Try this:

ip classless

interface Ethernet0
ip address 192.168.0.1 255.255.255.0
no ip directed-broadcast
ip nat inside

interface Serial1
ip address 66.87.193.2 255.255.255.252
no ip directed-broadcast
ip nat outside

access-list 1 permit 192.168.0.0 0.0.0.255
ip nat pool 101 66.87.193.168 66.87.193.191 255.255.255.244
ip nat inside source list 1 pool 101 overload
ip nat inside source static 66.87.194.161 192.168.0.2
continue with the others.

delete all dhcp commands
delete all rip commands

Just noticed in the Polycom config
DataLink Protocol = Frame Relay
DLCI 528 ATM RFC 1483 (Tunneling), which is MOATM

You need to talk to your provider and find out what encapsulation is being used.

jgercken,

Encapsulation is frame-relay ietf. Would this change the example config you provided? I test and try out the router every morning from 4am - 5am, the only time I'm allowed to. I was going to try your example config tomorrow morning, let me know if this changes anything. Thanks!
