I ve a router : linksys wag354G. i ve opened ports : 500 udp ; 4500 udp and 1701 udp. It works fine on Lan (with a workstation under xp pro) but out i can’t access server. In my router, perhaps there’s no ESP protocol support … :-( is there someone to help me please ? thank’s Author Posts Viewing 1 post (of 1 total) You must be logged in to reply to this topic.
