Ipsec tunnel traffic stop

Hi I created an ipsec tunnel from peplink to pfsenc firewall (on my other data center) everything work fine but after any amount of time (sometimes 20 mins, sometimes hours or days), traffic will just stop flowing even though the tunnel is up.
but sides, the peplink and the pfsens indicate tunnel status is up but still no traffic!

dose someone know this issue?
is there any log to the ipsec tunnel on the peplink router?

Hi there,

Thanks for the question. Peplink offically supports IPSec termination for Cisco IOS, Juniper and other Peplink Balances. Other services/equipment should ideally work as long as things are configured properly but official support is only for those previously listed.
