How can I configure the firewall of the Cisco 881W router so all LAN to WAN traffic is allowed?
Preferably how to do it by use of the CP professional tool.
So far I have configured the firewall with the CPP wizard and edited the Firewall Policy manually to allow TCP, UDP and icmp in the in-zone to out-zone section.
However all basic traffic like HTTP, HTTPS, Live Messenger ... passes through the router but a MS-VPN client installed on PCs on the LAN is unable to connect to the remote VPN-server.
First a PPTP connection is made, but after that, the logon screen never appears and a timeout popup shows up. When I remove all lines in the CPP Edit Firewall Policy (similar to disable firewall) the logon screen apears and a connection can be made.
What is used next to TCP, UDP and icmp to transport MS-VPN-Client packets? or did I forgot something else?
Any help appreciated,
