I have a PIX 506e (6.3.1), it works fine with site2site VPN from 3 years.
Last week ask me to make a new VPN with a brach office (I don't admin anything of the branch office), I create a classic VPN on my PIX (preshared key 3des sha), but it not works.
With command "sh crypto isakmp sa" I see the tunnel in QM_IDLE status like other VPNs, but traffic doesn't pass and the other adminstrator say me that it's firewall doesn't complete the authentications (is it possible?).
If I do command "sh crypto ipsec sa" I see the "send errors" what it's mean?
