IPsec Router - RV110W Does not nslookup after wan IP changes

Hello,

I have a cisco router RV110W with ipsec tunnel created to a zyxel router.

The RV110W has a static public ip. How ever the Zyxel has a dynamic IP so i am using dyndns to solve the ip changes.

Ipsec tunnel works fine until public IP from Zyxel changes, then it stops to work. Only after a reboot in RV110W it becomes normal again.

I'm thinking that RV110W router cannot do nslookup after a remote router IP change.

I already had to zyxel routers doing this IPsec tunneling and it always worked normally. Then for external issues i had to change one of them to Cisco.
