Hello and thanks for reading. I hope you can enlight me!
Two days ago we configured an IPSec VPN tunnel between our office (ZyWALL USG200) and one of our partners (Mikrotik router).
Yesterday when I arrived at the office, my colleague told me that the VPN connection was not working, I entered the USG ans saw that the VPN connection was up... but I noticed that I can't ping the other router... so something strange is happening. I disabled the firewall for one moment, and enabled it again and everything were working again... Today we've had the very same situation, it looks like there is a time out or something that stops the traffic.
Nailed up option is checked, and I don't know what can be happening.
Do any of you have an idea of what is happening?
Thank you very much!
Jud
