ArcreVich Hi all, I'd like to ask if such a confguration can work: I googled a lot and read this forum and found some clue that this might work, but please make me sure of the whole thing We have brach offices with natted connectivity : Office 1 has default gw with "public" address 10.10.0.6 natted by isp A, public address 1.2.3.4 Office 2 has default gw with "public" address 10.44.5.88 natted by isp A, public address 1.2.3.4 .... Office X has default gw with "public" address 172.18.3.4 natted by isp Z, public address 21.22.23.24 Inside every lan, "some" pc/smartphone/whatever should connect with vpn server 150.151.152.153, at the same time.... we expect hundreds ( but not thousands ) vpn at the same time connected to the server, after a double nat ( the first by the lan gw, the second by the isp ) I can not even guarantee that every office has its own internal private distinguished address space. Two offices could both have lan 192.168.10.0/24 The question : can this work ? I suspect yes... l2tp/ipsec and pptp/gre fail because they can handle nat but not multiple tunnels from the same natting ip to one server Hope I uses the right forum TIA Arcre
