Hi Please see the post "Basic Routing Problem" in this forum here is the link http://forum.cisco.com/eforum/servlet/NetProf?page=netprof&forum=Network%20Infrastructure&topic=WAN%2C%20Routing%20and%20Switching&topicID=.ee71a06&fromOutline=&CommCmd=MB%3Fcmd%3Ddisplay_location%26location%3D.2cc0ddaf

I made the changes that were suggested by the commentors and I stil lhave a problem I am able to ping and to trace from any subnet on our network to the remote router, but I when I try to ping FROM the remote router I stop at 10.150.0.2 which is our CORP lan interface.

So I can ping the inside interface of 10.101.0.2 on the remote rtr FROM any device on subnets 10.150.x.x and 10.1.x.x but I am unable to ping anything FROM the REMOTE router except the inside interface of 10.150.0.2 on the CORP router. Trace routes from the REMOTE rtr all stop at 10.150.0.2...any help would be very appreciated.

Thanks

On the assumption that the remote router is using a source address that the corp router does not know about, I would try these steps, on 10.150.0.9 make sure it's default gateway is 10.150.0.2 i.e. there is a line in its config

ip route 0.0.0.0 0.0.0.0 10.150.0.2

On the remote router use the extended ping as below, noting the lines

Extended commands [n]: y

Source address or interface: 10.101.0.2

Router#ping

Protocol [ip]:

Target IP address: 10.150.0.9

Repeat count [5]:

Datagram size [100]:

Timeout in seconds [2]:

Extended commands [n]: y

Source address or interface: 10.101.0.2

Type of service [0]:

Set DF bit in IP header? [no]:

Validate reply data? [no]:

Data pattern [0xABCD]:

Loose, Strict, Record, Timestamp, Verbose[none]:

Sweep range of sizes [n]:

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 10.150.0.9, timeout is 2 seconds:

Packet sent with a source address of 10.101.0.2

If it is not possible to use 10.150.0.9 with that default gateway use another machine that has 10.150.0.2 as its default gateway and can ping its default gateway.
