When running Thunderbridge connection between iMAC and macbook, opening VPN on one device kills the bridge. Is there any way around this?

Ha thanks yes too busy mixing terms.

I use the iMAC as a larger screen than the macbook. Its a 5K so i cant connect as an extended screen, but thunderbolt allows both screen share and allows me to drop files onto the iMAC to process on larger screen easily. But i run VPN on the macbook to my corporate space, thats when the bridge fails.

I just corrected the earlier reply to reflect 5K!

Yes TDM seems to be not supported on the iMAC5K box. Hence my trying a bit of a kludge to leverage the larger screen. It's the VPN that kills the connectivity..hoping there may be a networking fix that can get me around it.

Thanks for your help rkaufmann87. I found a chat somewhere that suggests this could be the VPN profile setup by our admin - causing a tunnel all via the VPN and effectively re-routing the bridge traffic via VPN...likely there wont be an acceptable fix from our corporate perspective!
