VPN Passthrough

Here's my issue, I have a 3rd party device that is on the local side of my Cisco ASA 5510 VPN router. This device needs to create a VPN tunnel through the 5510 router to a remote device, my issue is that i only have 1 ip address. I spoke with Cisco level 1 tech support and they stated the only way for the Cisco router to work the way i want it to would be for me to get a 2nd public ip address. This doesn't make any sense to me, i've done this sort of thing with other devices and they had no problem allowing the IPSEC traffic across the device.

I was playing around and think i almost had it configured the way i wanted but for some reason UDP port 500 was changing to port 4.

Does anyone know how to Configure the 5510 to allow the VPN passthrough I require.

Any assistance would be greatly welcomed.

Re: VPN Passthrough

You can set up several static IP VPN tunnels, this is done by using sequesnce numbers in your crypto map config. For each

sequence number, you define a new tunnel, with its own attributes.
