PPTP->Tunnel VPN (VLANS???)


I remember someone posting about being able to allow VPN/PPTP clients to be able to access a tunnel VPN with 6.3.1 with VLANS through the same PIX they are VPNed into. I have this need now and am trying to find some solutions. Here is the layout: -> PIX -> Internet <- PIX <-

VPN Tunnel between PIXs across internet

both internal networks can communicate fine with each other.

now I have several home users who PPTP in to the PIX and are unable to access the network. I believe this is due to the fact that the PIX will not allow requests that came in from its external interface, to go back out its interface for security reasons.

Is there now a way around this?

I would appreciate any links or documentation on how to implement this new feature.

Both PIXs are 506E units.

Thanks a lot

Re: PPTP->Tunnel VPN (VLANS???)

You still can't do this unfortunately, even with 6.3 code.

Well, I guess you could use the new VLAN support feature in 6.3, but it still means the clients need to connect in on a different interface than the LAN-to-LAN tunnel, that hasn't changed. You'd have to set up two external interfaces with two different IP addresses, have your clients connect in on one and have the LAN-to-LAN connect in on another. Even though these would physically be the one interface, logically to the PIX they're separate and so the re-routing works fine.
