Multiple VPN connections through PIX 525 running 6.3.4

We have several clients that need to VPN back to various coporate networks from my DMZ through and interface using PAT. Most are trying to use a cisco client using the normal ports ESP, UDP 500. Do these clients need a static translation or will it work through PAT?? I have nat transversal enabled on the pix, but hasn't changed anything.

Re: Multiple VPN connections through PIX 525 running 6.3.4

it works perfectly using PAT.

Make sure that UDP port 4500 is also open here as well on the PIX interface that receives the user flow - ie.e source interface the user is on - this is for transparent tunnelling.

That will resiolve your issue
