report a bug,may be a new features

Post by misaki » Sun Jun 03, 2018 6:00 am

this is my Topology。
1.the route has only one ipv4 address,the clinet networking throught nat function.
2.tcp protocol has been blocked by the FW,between Server and Route.But udp protocol is OK。ICMP is OK。

i analysis the SE VPN 。i found that .
1.when TCP was block,SEVPN use icmp and dns protocol exchange control message
2.if auth message was ok,use UDP(10004) send data part。

but when two client behind the router ,only the first connect client is ok。

i think

this problem is because the route was confusion。it don't konw the UDP date form server,give it to client A or client B.

Maybe use dynamic port to send data part is a great idea。

I think SoftEther VPN Server already use an isolated port for each VPN session.
