MR7500 M7 Blocking VPN clients with MacOS Tahoe 26
Hi, I run a MacBookPro M2 through a MR7500 Nighthawk M7 (on the Telstra network). I use OpenVPN client software to connect to a remote business network, and it has been running fine for years...
Hello!
After upgrading to macOS Tahoe 26, your MR7500 Nighthawk M7 on Telstra seems to block OpenVPN traffic—connections succeed but can't access the business network. The issue likely stems from how the M7 handles VPN passthrough or DNS post-update. Since VPN works fine via a separate hotspot or through ProtonVPN, try enabling VPN passthrough on the M7, switching OpenVPN to TCP, manually setting DNS, or forwarding port 1194. Also check for firmware updates or test with WireGuard if available. These steps may restore direct access without needing a tunnel-in-tunnel workaround.
Hi pemaj88983,
Thanks for the feedback.
I have checked for firmware updates, but appear to have the latest firmware.
Hardware Version 1.0
Firmware Version NTGX75_10.04.09.00
Software Version MR7500-1TLAUS_02_09
I already have VPN pass-through enabled on the M7. I disabled and re-enabled it, but this did not fix the problem.
Changing OpenVPN to TCP seems to have fixed the problem on my MacbookPro, however it has not fixed the issue on the iPhone or iPad. Although I can switch them to 5G to bypass the M7 unit.
Regards
Carl
