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

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

The link works fine for screen sharing but as soon as VPN tunnel is connected form one device it seems to kill the mac-mac bridge.

iMac, OS X Yosemite (10.10.3)

    Jaytee67,

     

    It's Thunderbolt not Thunderbridge.

     

    Can you elaborate why the iMac and MB are connected via Thunderbolt?

    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.

    Yup I see, have you considered using Target Display Mode instead using Screen Sharing? If you are not familiar with TDM please read Apple's FAQ on the subject at Target Display Mode: Frequently Asked Questions (FAQ) - Apple Support

    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.

    I see, well it looks like you have run into a limitation. I don't know of any solutions.

    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!
