When the issue occur again, please don’t change interface IP and keep the symptoms, we will check it immediately.
This is not real. We need that sites was avaible every time.
So I must change gw/ip.
Problems still persist. 2 vti in dead state. GWs are avaible.
2 ZW USG 1100. Less than 3 hours of work each. 1 of 2 VTI stops working.
Can't see each other. Other 15 VTIs work.
Caps from VTI.
It works fine as now
after we added another policy to block abnormal traffic coming up to USG
interface.Also, we found out
that, the connectivity check packet lost in ISP routing. You may check with ISP
A send connectivity check packet to B, B receiver the packet, and did reply.
However, A got no response from B.
Hi again. Today this situation returned again on 1 site. Both gw available, but vpn via main dont work. Help only switch ipsec vpn.
+1 to this count today
I will contact with you via private message to check if it is same as before that related to CC packets lost in ISP routing.
