Issue with a Tunnel

yozh
Hello,

Maybe Im missing something, or somehow miscofigured something, but I have a problem. 

I have a Tunnel going to inside from a IPv6 tunnel broker. (I know astaro can do that, but I`m having issues with licences, so I send the tunnel to inside device). SO I have a NAT rule IP Protocol 41 to inside device, with auto firewall rule. This always worked with out issues, at some point after installing updates or just rebooting a node from HA the tunnel would not comeback, then after few days it would restore it self, or if I rebooted the master node it would comeback. I did a lot of capturing and examining and I cant find anything wrong, I see tunnel broker IPv4 initial traffic, but tunnel would not establish. Almost seems like the NAT table gets stuck or something. Anyone seen issues like this before ? Also anyway to manual clear NAT table ?

    Hi, 

    Did you check the logs?
    (firewall, IPS, app control)
