I am using Radmin VPN to create a remote access VPN between my home and office computer. On the office computer, I created a network bridge (in windows) to bridge the VPN network connection with the LAN connection so that I can use remote desktop and SSH to access other computers on the office network from my home computer.
To do this, I first created the bridge by selecting the VPN connection, followed by the LAN connection and selecting "Bridge Connections". This created a network bridge which had an IP address on the same subnet as the other office computers. I then gave my home computer an additional IP address in the VPN connection that is on the same subnet as the office network computers. So far, I am able to ping the office computers and access Remote desktop and SSH from home. However, I am unable to directly ping or RDP into my office computer (the one hosting the VPN connection) when the bridge connection is enabled. When I try to ping it's LAN IP address, I get a "TTL expired in transit." error.
What does this mean and what can I do to fix it so I can also ping and RDP into my office computer? Everything else seems to work fine except for this.
Looks like your problem is you're trying to connect using the Radmin IP that is no longer valid. Maybe you can try to find a valid IP for your office computer within the Radmin network IP range or use a separated machine for rdp the office computer.
