I have a pair of XG 310s in Active/Standby at customer prem working fine. From there I have a site to site VPN tunnel to my Data Center in a nearby town terminating on a Cisco ASA Firewall context. The two Local customer subnets are the one for local traffic at the customer's site (192.168.0.0/16) and a subnet carved out for the Remote Access VPN users still working from home for Covid, a /24 carved out of the 10.0.0.0/8 space. This tunnel comes up fine and both IPSec SAs come up and traffic passes no problem. However, eventually the SA between the RA users (the 10.x.x.x/24) and the DC subnets (also in a 10.x.x.x/24 net but not overlapping) gets hung. A bounce of the tunnel brings it back up.
Any suggestions on what could be causing this or how to fix it?
Thanks,
