This is regarding VPN pass-through, I have a Sonicwall Firewall configured as a VPN Server. I can connect to VPN from firewall outside interface, but I cannot connect it from router outside interface which is internet. Does Cisco 1841 block VPN traffic by default (Not passing through). I purchased the firewall with basic software.
