WC7500 and remote WAC720 issues

Ok, these are getting annoying.  Site #2 had public IP change so had to rebuild VPN tunnel no big deal just changed the IP on HQ side to their new IP and tunnel was back up and the WAC720 rejoined the WC7500 and all was good.  Within 30 seconds of that site #1 goes down hard.  Can not get it back up.  Even put a new WAC720 in place of existing.  VPN tunnel to site #1 never went down and is still up.  I can reach everything on that side including the WAC720 from the same subnet that the WC7500 controller sets on at HQ.  However the WC7500 can not ping the AP or anything on that subnet across the tunnel.  WC7500 can ping all local IPs and public internet addresses.  The VPN tunnel is not issue as it is wide open and nothing changed.  So why did the WC7500 just forget how to reach the subnet on the other side of the tunnel when all other devices on that subnet can do it?  Sure this is why I can not connect the AP on the other side, but question is why?

 

 

  • This one falls on the firewall.  Some odd bug where updating one tunnel caused the other tunnel to have issues.  I changed a few things on the tunnel, and then changed them back.  That fixed it even config ended up identical to what it was.  I wont call out the specific vendor, but 3 vendors in play Fortinet, Cisco, and Meraki.  To be fair all 3 are old devices as well from each vendor none are currently being marketed, but only 1 is actually past end of support date.
