All,
I am having issues with IOS content filtering and a VPN tunnel connectivity. I installed a 1941 router at a branch office and configured it for internet and an IPSEC tunnel back to Corporate Office. Everything worked PERFECT.. Internet was up and tunnel was up (ping both ways)... Then I configured IOS content filtering for the branch router, and content filtering started working perfect as well, BUT the tunnel would ONLY work one way... As soon as I un apply the content filtering the tunnel works BOTH ways again. I attached a simple diagram if you need a visual, but her goes nothing
IOS content filtering is NOT applied:
10.0.0.0/24 network can ping 192.168.81.0/24
192.168.81.0/24 network can ping 10.0.0.0/24
Internet is UP
Tunnel is UP
IOS content filtering is applied:
192.168.81.0/24 network can ping 10.0.0.0/24
10.0.0.0/24 CAN ONLY PING 192.168.81.1 (NOT ANY PC like .100)
10.0.0.0/24 CANT PING 192.168.81.2 - 254
Internet is UP
Filtering is UP
Tunnel is UP
CORPORATE CAN ONLY PING LAN INTERFACE OF BRANCH ROUTER.... NO PCs
I have attached a diagram and the config of the branch router..... Any help would be greatly appreciated
