I have an IPsec VPN config which uses UDP 500 and UDP 4500. After adding a basic ZBFW config to block unsolicited incoming connection. I noticed my VPN is flapping occasionally. Since it does not occur consistently, I suspect it has to do with session timeout.
This is a VPN client, I do not want to add bypass for all UDP 500/4500 traffic. Is there a global config for ZBFW UDP timeout? The CBAC config "ip inspect udp idle-time 60" does not work anymore.\
On a related note, what is the default UDP session timeout for ZBFW?
