Hi,

You need to give us more information about the problem. Are you able to ping across the tunnel ?

Which ip address you are doing a traceroute to..? Where does it go ?

Here is more information:

Have 4 remote locations and 1 main.

**Currently Remotes can't access each other not even ping. IE from remote 1: 192.168.1.X can't ping remote 192.168.3.X.

All Remotes can access Main location. All internet traffic has to go through main router. 192.168.0.11

** POP MAIL can't be accessed from Remotes.

** Account Software can't be used at remotes. The accounting software is installed on local machines but access information from request2.paydata.com and request.paydata.com remotes can't trace to this fails at main router.

Hi,

Couldn't find 192.168.3.0 in the config you pasted. Assuiming, its one of the remote n/w , you are missing the deny statements in the access-list 101. e.g.

access-list 101 deny ip 192.168.1.0 0.0.0.255 192.168.3.0 0.0.0.255

access-list 101 deny ip 192.168.3.0 0.0.0.255 192.168.1.0 0.0.0.255

You have to put the similar statements for every remote router.

*Please rate if helped.

Thanks for that help however what about not being able to access certain items like the accounting software and Pop Mail which should all come from the main router? All internet traffic needs to go through the main router. I tried putting in the ports for the accounting software but that didn't work. Am I missing something to allow the accounting software?

Hi,

On the vlan in terface on Main router, the tcp mss is set to a very low value. Some applications require the packet size to be greater.

interface Vlan1

ip tcp adjust-mss 1100

exit

Try increasing the tcp mss size to see if there's any success.

bumped

ip tcp adjust-mss 1400

Still no luck if I bump any more can't get into database that is at main site from the remote.

database gives socket error. They said check ports which I have open on both ends.
