We have a Cisco 677 ADSL router that acts as a firewall and proxy for our internal network. I would like to set a VPN with our external webserver and other office sites. Internally the VPN server is a MS w2k server with VNP setup. I have opened up ports 1723(tcp), and 1701,500(udp) which MS VPN works on. Have not had any success connecting. Does the 667 have the ability to aid vpn connections? Are the other port numbers I have to open up. Is it possible to open up IP ports? Thanks for responding.
