either way...that was the closest i've been to getting this working...its been 'server did not respond' ever since. Notice that the server never sends an UDP-ESP packet. In that case I'm barking up the wrong tree with certificate troubleshooting...I can't even establish a connection with preshared keys. over here That is all.

I have configured RRAS with the pre-shared key and also the XP client. i have a choice of IPSEC and >> >> IPSEC (offline request). >> > >> > Those aren't different certs, just different ways to >> > issue them (I believe.) >> In RRAS on win2003...RRAS properties...security tab...'allow custom ipsec policy for l2tp connection'...type in a preshared key in the provided field. > >> i'll have to give this a try...do you know Any help would be appreciated? -- Bruce J MCP, MCDST, Network+, Security+ Bruce J, Jan 10, 2008 #1 Advertisements Bruce J Guest I have since discovered by using "netsh ipsec

I haven’t even try with certificates, just with a shared key, which is indeed the same in both machines. http://developers-club.com/posts/128742/ Windows Server TechCenter   Sign in United States (English) Brasil (Português)Česká republika (Čeština)Deutschland (Deutsch)España (Español)France (Français)Indonesia (Bahasa)Italia (Italiano)România (Română)Türkiye (Türkçe)Россия (Русский)ישראל (עברית)المملكة العربية السعودية (العربية)ไทย (ไทย)대한민국 (한국어)中华人民共和国 (中文)台灣 (中文)日本 (日本語)  HomeWindows Had some similar VPN problems that got resolved .
