Softhether on Hyper-V

Post by MichelloMainecoony » Wed Apr 26, 2023 12:24 pm

Hello all.

I have issue with VPN Server on Hyper-V.

I have Hyper-V as my virtualisation server. I installed Ubuntu Server in VM. VM has 2 network interfaces. For example, configuration network interfaces:
eth0 (external): 213.111.222.211, subnet 213.111.222.208/28, with dns
eth1 (internal): 163.122.188.16, subnet 163.122.188.0/24, with dns
I can ping external resources (sites, google dns) and can ping my internal resources (servers, vms, sites) in my local network. Also, I can ping my external ip (213.111.222.211) from Internet.

When I installed Softether VPN Server on this VM and configured it with NAT, Virtual Hub and Local Bridge to eth1 with radius authorisation in AD, my ping was dropped. 70-80% of packages were dropped. And of course, my connection couldn't be established to this vpn server. Sometimes connection was established.

I can't find where I made mistake. Two yesrs ago I had the same configuration vpn server, but I use esxi as virtualisation.

P.S.: I understand that i must use firewall in VM and close icmp. I open it only for test and icmp will close when I resolve this issue.

I noticed you are using two different public IPs. What does your routing table look like?

Code: Select all

ip route show

I resolved issue.
There was wrong network link configuration on Hyper-V. Some engineer was not enough qualified.
