PAT all Internet source address to a specific internal address by PIX

Starting with PIX 6.2, NAT and PAT can be applied to traffic from an outside, or less secure, interface to an inside (more secure) interface. This is sometimes referred to as "bi-directional NAT."

So If all Internet outside addresses are be "bi-directional NAT" to a specific internal address, and because the PIX also used for IPSec VPN connections and VPN clients (internal local address pool), I am just wondering whether it will be impact on the IPSec VPN connections or the VPN client access functions?

Any comments?

Thanks in advance.

Re: PAT all Internet source address to a specific internal addre

Inbound NAT shouldn't have any effect on your VPN clients or LAN-to-LAN tunnel. In fact, for the VPN traffic you would have added commands to specifically bypass the NAT functions within the PIX, so there's no problem with doing both.
