Internet access to remote LAN

Hi Attached is my network config where i need to give internet access to the LAN A users. At present LAN A users are using oracle on 64K circuit, the oracle server is on LAN B. I am using RIP.

The problem is i can ping every PC in LAN B but not the Internet Router.

i want to know,

why i couldnot ping the internet router's ethernet interface from LAN A.?

What changes is required in ROuter A & Router B's routing.?

Regards

Re: Internet access to remote LAN

First of all, does ur Internet router know how to get to LAN A? Does it have a route to LAN A? You mentioned that u're running RIP btw RTR A & B. But are u also running RIP btw RTR B & RTR Internet?

Make sure RTR Internet knows how to get back to LAN A.

Does the internet router requires a route to LAN A? whatif i put a static route in RTR B

iproute E0

No it does not have route to LAN A? Is this reason i cannot ping internet router ethernet from LAN A ?

There is no RIP between RTR B & RTR internet?

Re: Internet access to remote LAN

Hi

Adding a route on Rtr B doesnt solve the problem. The problem is on ur Internet router, in which it doesn't have a route entry for the LAN A network. The Ping packets successfully reaches ur Internet router, but when ur Internet router tries to reply with icmp echo, it looks up it's routing table and does not find a route entry for LAN A's network address. Therefore, it doesn't know how to route it back to LAN A, and it drops the echo replies.

HTH.

Re: Internet access to remote LAN

if i am correct, if i add a route in internet router

ip route RTRB E0

this would give the internet access to the LAN A users ?

Yes..with this static route pointing to rtr B's int e0 ip address, it will work.
