I have a Cisco 1841 connected to my ISP with the WAN port configured for DHCP. I have a /30 subnet with public addresses (no NAT) configured on my LAN port. I'm having trouble configuring RIP to advertise this local subnet to my ISP's upstream router. I'm getting an IP from my ISP and from the router console I'm able to ping a host on the internet, however I'm unable to communicate with any host beyond my local 1841 router if attempted from a host on the LAN. The same solution works fine on a smaller residential Linksys router with minimal effort. Below is my current config. Any help would be greatly appreciated.
ip address 69.x.x.x 255.255.255.252
ip address dhcp
