Description

I'm trying to connect to a cisco vpn router using the wrt320N and build 13000. I'm running linux on my computer and connecting with the cisco linux client. I just want the router to pass the vpn connection through it but it doesn't work. If I hook my computer directly up to the modem, it works but if I try to connect through the router, it does not. This was an issue on my old dlink dgl-4100 router until I disabled SPI (stateful packet inspection). I tried disabling SPI through DD-WRT on the wrt320n but it still does not connect. I also have ipsec passthrough enabled under Security -> VPN passthrough. I think perhaps this setting is not working yet? Is there anything else I need to do to get it to connect using ipsec over tcp?

Also I tried putting my computer on the dmz but it couldn't connect either with that method.

Router: wrt320n Firmware: DD-WRT v24-sp2 (09/30/09) big - build 13000M NEWD-2 K2.6 Eko Cisco Linux VPN client: 4.8.02.0030

I should also add that I have tried connecting using Windows XP and the windows cisco vpn client but that doesn't work either through the router.

Niels on the Linksys WRT320N now supported forum verified that it is not passing through GRE packets and that wrt54g running DD-WRT v24-sp1 is able to pass through IPSEC packets.

It appears this may be related to ipsec tcp tunnels since it has been confirmed that ipsec udp tunnels work.
