Hello Chaps, I need to get a VPN working to a client site. Problem is that for one reason or another they do not want to configure inbound rules, only outbound, on their firewall (PIX). For this reason I will not be able to initiate the connection to our VPN end-point on the client network and instead will get this VPN end-point to send keep-alives to my end every so often to keep the VPN online.
My problem is what protocol to use LPTP or IPSec (IKE, AH, ESP). Their network is on a 1918 and so the encrypted packets will need to flow through the NAT table on the PIX. On top of this, because of the lack of inbound connections, I guess it also needs to be statful so that the PIX will allow the return connections.... I know that by allowing GRE on a pix the above will work for PPTP (and would assume LPTP) but ideally I want to use IPSec. ALSO, I just want to know how it works 'cause I thought state worked on layer 4 - so in tunnel mode how does the state table work for the PPTP connection? Does this make sense? Any ideas would be very much appreciated. Thanks!!
