comment Pfsense 2.02 ipsec vpn tunnel goes down randomly
Or if we use an unused lan ip as the PPTP server ip will the pptp work? we have only option to provide our public ip (Wan ip) as the gateway to our clients.

Chirs -> Thank you for your reply.The PPTP sever ip is the WAN IP itself.Since our ISP provides only one static ip for us and my doubt is that which ip should be given to the PTTP server then? or In order to make the ispec and pptp server working we need multiple WAN ip?

> Thank your for your reply.I believe pptp is configured correctly.The same configuration worked perfectly only my old pfsesne(1.2.3).One day before i have disabled nat-t and unchecked Prefer older IPsec SAs but still the VPN went down where there is not activity(normally at night).
