Local bridge not working

[captainkent]

I first tried to create a Local Bridge using an onboard Realtek ethernet adapter, which gave me an error.

I've currently replaced the onboard Realtek ethernet adapter with an Intel Gigabit adapter, which gives me the same erorr.

I'm running SoftEther from FreeBSD. Any ideas?

Local Bridge. (I guess this is correct?)

Using Local Bridge.

I've been doing some research. And it seems I need to setup some sort of tap, tun or bridge device between my Local Bridge and physical network adapter.

I set up a bridge device using the following commands.

# ifconfig
em0: flags=28943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST,PPROMISC> metric 0 mtu 1500
options=4019b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,TSO4,VLAN_HWTSO>

status: no carrier
lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> metric 0 mtu 16384
options=600003<RXCSUM,TXCSUM,RXCSUM_IPV6,TXCSUM_IPV6>
inet6 ::1 prefixlen 128
inet6 fe80::1%lo0 prefixlen 64 scopeid 0x3
inet 127.0.0.1 netmask 0xff000000
nd6 options=21<PERFORMNUD,AUTO_LINKLOCAL>

# ifconfig create bridge0
# ifconfig bridge0 addm em0
# ifconfig em0 up
# ifconfig bridge0 inet 10.1.1.52/24

Doing this, I can ping the bridge's IP from within my network, meaning it exists.

I then set up the Virtual Hub to connect to the bridge0 device, but now it says my device is offline.

Any suggestions?

I went ahead and created tap and bridge interface instead. I added the tap interface and my physical network interface to the bridge interface.

I then connected to the tap interface through the SoftEther Server Manager. I still see that my Local Bridge is offline.

This is the output of ifconfig.

Could you try to create localbridge to em0?
