Configuration Issue

Daniel Eboa

Hi Guys,
Am facing an issue with a configuration on cisco 1841 router.

I have 2 network interfaces on the router
F0/0 connected to ISP1 via PPPOE with a Dialer0 Interface
F0/1 connected to ISP2 via dhcp

A 4 ports Switch connected to LAN via Vlan1 Interface.
on the Vlan1 interface, i have configured 2 subnets (10.237.19.0/24 and 10.237.18.0/24)

My problem is this:

I want subnet 10.237.18.0/24 to go to internet only via interface F0/1
I want subnet 10.237.19.0/24 to go to internet only via interface F0/0 > Dialer0
I want to map port 80 and other specific ports on the interface Dialer0 with a host in subnet 10.237.19.0/24

Please can someone help me with a sample config to match my needs.

Thanks.

This is probably your homework, but I was really bored and felt like typing...

ip access-list extended SUB18
   permit tcp 10.237.18.0 0.0.0.255 any eq 80

ip access-list extended SUB19
   permit tcp 10.237.19.0 0.0.0.255 any eq 80

route-map FILTER permit 5
   match ip address SUB18
   set ip next-hop [B]<IP_OF_ISP2>[/B]

route-map FILTER permit 10
   match ip add SUB19
   set ip next-hop [B]<IP_OF_ISP1>[/B]

interface [B]<LAN_side_of_router>[/B]
   ip policy route-map FILTER

ip nat inside source static tcp [B]<ip_you_want_to_map>[/B] 80 interface Dialer0 80
