Multiple firewalls on same public subnet
I have a /29 subnet provided by ISP and on this i have 2 x USG40 (ours) and 1 x sonicwall (not ours) with setup as follows
ISP managed Cisco gateway 220.127.116.11/29
the problem is if the USG's lose power or WAN link they will not reconnect whilst the Sonicwall is online. Disconnect the Sonicwall and refresh the WAN link they connect ok, reconnect Sonicwall and all 3 work fine until USG's loses power or WAN link.
Anybody any ideas
