Ipsec over TCP on Pix

Good Day,

I would want to know if there is the possibility to configure IPSEC over TCP on the pix Firewall.

The last Pix OS (6.3.3) support this features?

Thanks

Diego

Re: Ipsec over TCP on Pix

The pix doesn't support ipsec over tcp. It supports NAT Traversal that is ipsec over udp. IPSEC over tcp is only supported in the VPN concentrator. The following link talks about NAT traversal.

Take a look at this link for Configuring IPSec over TCP on a VPN 3000 Concentrator
