Hello, i want to install a router with two interfaces fastethernet between my Lan and a prolan as a firewall.
Lan-----Router/firewall----RouterProlan------Network's partners/RoamingUsers
I have configured only the routing and Nat without filtering but it don't work
I can ping only the 192.168.51.0 network but no others networks in the prolan. And roaming users cannot access to Lan
Any help
It's 1721 router with a Cisco 4-port 10/100BASE-T Fast Ethernet Switch WAN Interface Card (WIC-4ESW)
Thanks

please provide a "show ip route" output.
please provide the source & destination addresses you're trying to get to communicate.
also, i dont see a proper network for VLAN1 begin serviced by OSPF.
your OSFP is servicing:
10.166.50.0/24 and (network 10.166.50.0 0.0.0.255)
10.166.0.0 - 10.166.3.255 (network 10.166.0.0 0.0.3.255)
where is the VLAN1 network 10.166.10.0/22 in ospf? if your source network is 10.166.10.0/22 and you have no static routes on the other routers for this network, it should not work. you need to get OSPF to advertise 10.166.10.0/22.
a better OSPF network entry could be:
network 10.166.50.0 0.0.0.255 area 0 (advertise 10.166.50.0/24)
network 10.166.10.0 0.0.3.255 area 0 (advertise 10.166.10.0 - 10.166.13.255)

oops...did i do my 10.166.0.0 0.0.3.255 calculation right? verify plz...may have mistated this....
also, since your access-lists in use on the interfaces allow all IP, then remove them for a test without them to see if you get different results.

I tought network 10.166.0.0 0.0.3.255 area 0 is to advertise the 10.166.0.0 /22 network isn't?
But i made a mistake here my network is 10.166.8.0 /22
So opsf command should be network 10.166.8.0 0.0.3.255 area 0 is it right?
I have the same problem with or without access-list
Also i have the same problem with a static route
For exemple Destination adress 192.168.53.7 (host in the partner metwork via the prolan) Source address host 10.166.11.30 /22
I have the problem, even if i enter an ip route 192.168.53.0 255.255.255.0 10.166.50.1(the prolan router). And i ve a default route ip route 0.0.0.0 0.0.0.0 10.166.50.1
Lan---------------routerfirewall--------Routerprolan
10.166.8.0/22 F1 F0 10.166.50.1
The interface F1 is the first interface of the WIC-4ESW i ve plugged a cable from F1 to the Lan switches
I ve putted F1 in vlan 1 because i cannot enter an ip address to F1
is it correct config?
