SoftEther VPN User Forum

Hi @all!

i built up a l2-bridge LAN-to-LAN. In the administration GUI everything looks fine, but no communication comes through. Regarding to troubleshooting my configuration of VPN is wrong. I can not find the misconfiguration. I tried a lot of stuff, read the softether manuals several times. Nothing helps!

A short history/overview:
- Both sides are in the same net (192.168.128.162 and 192.168.177.23 in subnet 255.255.0.0)
- used components: VPNserver and VPNbridge
- connection is established (both sides are displayed as online)
- used network adapters are locally bridged and system is restarted several times after that
- when refreshing status view incoming and outgoing unicast and multicast packets are counting up
- the iptable of the session displays a lot of IPs of both sides
- SecureNAT is disabled, IPsec/L2TP is disabled, OpenVPN/MS-SSTP cloning is disabled
- no obvious reasons/errors for that silence listed in all standard logs


Result of ping on both sides looks the same, here example of bridge-side to vpnserver:
bridge:~$ traceroute 192.168.128.162
traceroute to 192.168.128.162 (192.168.128.162), 30 hops max, 60 byte packets

It seems like you are trying to ping an IP address that is on a bridged physical interface. Any IP address that is on a bridged physical interface is inaccessible to the far side of the SoftEther bridge.

The "eth0.99" and duplicate MAC address suggests that you are trying to alias a single physical interface, which causes two additional problems:

1. Logical aliasing just won't work like you expect.
2. /sbin/ifconfig style aliasing is deprecated.

Interfaces that have more than one IP address should be specified in the /etc/network/interfaces file (or equivalent) without a prefix like this:

iface eth0 inet dhcp

iface eth0 inet static
address A.B.C.D
...

iface eth0 inet static
address E.F.G.H
...
