Problem connecting with mobile client…

[ragtag]

I'm having trouble setting up mobile clients with IPsec.

This is the error I get, and I don't know why. The server has a static ip and the client a dynamic o
ne (the client is an old iBook running OS X tiger using the built in VPN client).

Phase 1 seems to work, phase 2 seems to work too, as I read on the forum that I could ignore the pol
icy does not exist error. It waits a while after those errors, and then disconnects.

Anyone know what's wrong here? Or just how to set up a system where mobile clients can connect to IP
sec (I'm new to VPN in general).

Cheers,

ragtag

This is just a hunch. Since you didn't specify the release you are running on.

Try disabling PFS on the server and/or the client side for this mobile connection.
PFS == Perfect forward secrecy - Diffie Hellman group 1,2,5, or none.

Kind regards,

Seth

Sorry, forgot to mention the pfsense version, it's 1.2-RC4 built on Tue Jan 15 23:05:07 EST 2008

PFS key group, if that's what you mean, has been set to off on the server. I'm not sure how you set PFS on the OS X client, it's somewhat limited in options. Tried setting it to 1,2 and 5 as well, but it seemed to have no effect.
