Hi Expert ,

Can you share experience for how to configure  dyndns using fortigate .

Site1 static ip and fortigate 110c
site 2 dynamic ip and fortigate 80c

My question is how to configure ipsec tunnel using dyndns ?

the most common problem is that phase one needs a fixed name or number.
Using dyndns you can use a name for that part.
The Phase 2 part is tunnel only, and should work anyway.

you can register a name with dyndns ( and keep it up to date)  on the dynamic site. Then the tunnel can be built two way ...

The other option is to make a roaming tunnel. Then on the static address site you need to tell the remote = 0.0.0.0 , meaning anybody can try to build a tunnel not just the other party.

I need to lookup some old fortigate manuals for that one.

Page 646 describes how to setup a phase one. It also mentions a dyndns name as remote host spec.
