Hi there,

I have a point to point connection but have come accross an issue.

Site 1 - This is the main office and this has the following setup

router internal 10.1.15.230 ( Wan Link 10.2.254.1 )

Site 2 - Branch Office

router internal 10.2.0.1 ( Wan Link 10.2.254.2 )

Now This is where I am confused, I am able to send ping commands
through the router Interfaces and so know the link is up and running.

I have a computer attached at the remote site on ip address 10.2.0.10
going through the router 10.2.0.1 Now when I am at the london office I
am able to do a tracert and it comes with the following

1 <1 ms <1 ms <1 ms 10.1.15.230
2 14 ms 14 ms 14 ms 10.2.254.1
3 14 ms 13 ms 13 ms 10.2.0.10

When I then Remote connect to the Computer and try and tracert or ping
any london addresses 10.1.14.40 as an example then it comes up with
the following

1 <1 ms <1 ms <1 ms 10.2.0.1
2 * * * *

This is the IP Route from the Remote router.

Gateway of last resort is 10.2.254.2 to network 0.0.0.0

D EX 204.71.220.0/24 [170/3077120] via 10.2.254.2, 1d16h, Serial0/0/0

Can any one offer any advise on how to get the remote site to see the
main site.

Many Thanks

I'm guessing that this is just a typo, but your information above says
the WAN link on the central office side is .1, and yet your routing
table on the remote router shows next hops of .2 which doesn't make
any sense. Have you tried sourcing trace routes (type trace and hit
enter) and source it from the LAN and WAN to see what happens. But to
solve this quickly, please post a show ip route from both routers and
your configs (password and other information omitted).- Hide quoted text -
