Windows 2000 VPN

I have a 2621 router and want to allow L2TP through for a VPN connection to a server. What IOS commands do I need to use to open the correct ports/protocols?

Thanks

Irvin

Unless you’re locking down your traffic with access lists or the firewall feature set, L2TP should pass properly. Read the section on “Configuring the Firewall to Allow VPN Packets” at this url http://www.cisco.com/univercd/cc/td/doc/product/aggr/vpn5000/5000sw/conce60x/5001conf/ipsec.htm

I am using the firewall feature set in the 2621. Any other help?

As i understand it right, the tunnel is not ended on router. Than you just have to allow L2TP (ip protocol 115) to pass you router. So you have to modify your access list on out interface for inbound traffic like this : in global configuration mode "access-list number/name permit 115 source_address complementary_mask destinatination_address complementary_mask" and in interface conf mode "ip access-group number/name in". Now is your L2TP traffic passing your firewall.

Hope it helps.
