    Does anybody know if Tomato can do VPN pass-thru? If yes should it work by default or do I need to change some settings somewhere?

    The problem is that I use an IPSEC vpn client to connect to my office and on my WRT54GL (V1) router when I had DD-WRT installed I enabled the VPN pass-thru in the firmware and everything worked great. With Tomato I have identical settings (port forwards etc) but cannot find a section to enable the pass-thru and cannot connect to the VPN with the client. I have searched the web and this forum but cannot really find anybody else with this exact problem.

    Any help would be greatly appreciated as I really like the software and this is the only issue I have with it so if I can get this sorted it would be perfect.... If Tomato can not do VPN pass-thru could it possibly be added to a wish list for future versions?

    Many thanks for any help in advance.....

    I have used two different IPsec VPNs with no issues on all Tomato versions.

    Witch ports do I need to forward? I have a Linux behind the wrt, pptp works fine, now I want to switch to ipsec and openvpn on the Linux.
    Thx for your help

    For OpenVPN you just need to forward the port on which openvpn is listening.
    As far as IPSEC goes - you have multiple ports depending on the software you use. You normally have port 500 for the key exchange, 4500 in case of NAT-T plus whatever port and protocol the vpn server listens on (this can be configurable).
    And by the way... "IPSEC and openvpn".. those are two different animals.. openvpn is an ssl vpn, not an ipsec vpn. ssl vpns use ssl known from webbrowser, which has been around longer and is less involved than ipsec vpn, plus it is more firewall friendly (requires only one port and can use the web port.. I have my openvpn server running on port 443 so I can connect even from places with strict firewall rules.. the https port is hardly ever blocked - unless somebody wants to block all web traffic).
