Upgraded to 20.7 now Wife cannot connect to work - I'm in trouble - any ideas

[tre4bax]

Yesterday everything was fine.  Last night I upgraded to 20.7 and today she cannot connect to her work.

Their system uses Blackberry secure and it no longer attaches on either Wifi or LAN.  I did not changes other than to upgrade to this version.

Anyone have any idea what is new about 20.7 that could cause this issue?  Everything looks good, and all seems to be working normally other than this.  I wondered if something has changed about allowing VPNs or something?

I noticed something changed with the interfaces on 20.7, so I would check whether by chance, an interface got disabled, and, most importantly, restart the firewall once or twice to make sure these new changes have fully kicked in. You might want to have a look in the system log to see if something's up with them, not coming up, strange names that don't match the old names etc.
Look in the interface assignments if everything is still assigned correctly.

I had a couple issues with having hardware acceleration enabled (which seemed fine prior to 20.7), disabled that, rebooted and the odd-ness stopped.  Can't say it's related to connectivity though.  There is also a new issue for some with ipv6 taking some time for hosts to obtain an address (stateless), but no issues with ipv4. 

Are you sure it's not on the blackberry service/server itself?  Coincidence maybe?

Thanks both,  I have IPv6 switched off.

I have noticed my wireguard has also gone defunct so it could be that something has changed with regard VPNS.

I will keep poking.
