Cisco 1720 Router

By larrynorthwood ·
I have a ISP frame relay connection to a Cisco 1720 router that has one ethernet port. The router is then connected to a 3com superstack firewall. We have been assigned xxxx.xxxx.xxxx.152 - 155 mask 255.255.255.252 as available Internet addresses. Serial address for router being xxx.xxx.xxx.89.
The network is currently using NAT for private network address range 192.168.0.0. I have been assigned some additional Internet addresses to provide Internet WEB servers. Can someone assist with commands required to route the new address range thru the router xxx.xxx.xxx.136 -143 mask 255.255.255.248 Thanks

Assign the new range to the router's ethernet interface as a secondary address, ie:

ip address x.x.x.153 255.255.255.252 secondary

This is assuming that this new (very limited) range will be directly connected to the ethernet on you router (noother router in-between) (switches/hubs OK)

No routing changes are necessary, since the ISP assigned you those addresses, they will also route to you.
