Dear Mkt Forum
I have a problem with OPENVPN client Side when try to connect from ANY Natted LAN to Server.
The server already has N.3 OpenVPN Client connected successfull, the RB client that not work, with same configuration, work fine from our Office Natted LAN, "when i think no problem with configuration" but when we try to connect the same RB with same config from customers Natted LAN no work.
When RB Client try to connect from Customers Natted LAN the packed arrive to Server Side because we See the LOG in RB Server but i think that problem is in Return packet.
With Traceroute, i've seen that maybe double external NAT from ISP, because external IP of connection that provider operator see is 37.x.x.x but the packet in the Server Side Arrive with address 95.x.x.x and we think that there is any problem with ISP double NAT connection.
Anyone know if is possible to bypass these problem ?
thanks in advance for your support.
PS: for best reliable do you think that is better L2TP/IPSEC or OPENVPN ???
