F5 Big IP VPN client refusing to work with Eero 6?
Any known issues between Eero 6 (not "pro") with the latest firmware, and F5 Big-IP VPN clients?
A company I work for is using an F5 BIG-IP Edge Client for its VPN (as well as hardware VPN boxes like HPE Aruba), and it's been working well for me for the past few years with a variety of routers.
Eero 6 doesn't like it over either WiFi or wired connection, including with the Aruba box. Notes:
- behavior repeatable and reproducible with my two work devices - over either the software VPN client - or the Aruba box
- this is really weird: connecting my old WiFi router downstream ("in front") of Eero - and then connecting my devices to it rather than to Eero directly - and all is well (what?). So it seems that it's not about Eero dropping packets or refusing something from my devices - but more about the VPN client not liking something about direct connections to Eero...
- When attempting to connect to the Aruba's WiFi, my MBP complains "authentication failed" and "cannot contact authentication server";
- HPE Aruba box shows the green light - thus supposedly connecting - yet no VPN
Thanks for any hints and tips.
Thank you for bringing this topic up. If you wouldn't mind, can you please email this information to email@example.com? If you do, can you then direct message me with the email address you used so I can work on getting this escalated up to our Tier 2 for investigation? I have also included an article below so you can choose a different form of contacting our support if you would like.
Issue resolved with the help of Eero Support (thank you).
Root cause: network mask was set to 255.0.0.0, as opposed to the usual 255.255.255.0 for most home networks. Once the network mask was changed to 255.255.255.0 (Settings - Advanced - DHCP & NAT - Subnet Mask (via "Manual IP")) - the VPN client started working.
Why was the network mask set to that unusual value? I can't be 100% sure but suspect it wasn't me: I don't remember touching it, and wouldn't set it to something like that. I suspect it's default value for "Manual IP" - something Eero Support might want to double-check.
