VPN

I am running a Site to Side VPN with one DynDNS Site.

When now the IP of the DynDNS is changes, the VPN Tunnel crashes down and never comes up again.

The only way is to click on "Save" in the IPSec Config of the monoWall on the Site with the Static IP.

DPD is activated on both Sites with 30Sec.

Can someone help me?

Here is the Config:
Site1:
LAN: 192.168.50.0/24 IP LAN 192.168.50.1
WAN 92.xx.xx.xx

DPD 30 sec
IPSEC Interface LAN
Local Net - LAN subnet
Remote subnet: 192.168.1.0/24
Remote gateway: xxxxxxx.dnsalias.com
Description: m0n0-to-m0n0-test


Phase 1
Negotiation mode Agressive
My identifier FQDN (yyyyyy.dnsalias.com)
Encryption Algoritm 3Des
hash Algorithm MD5
DH key group 2

m0n0wall_2:

I've this problem too , I've found that /usr/local/bin/dnswatch still get old IP when IP of the DynDNS is changed.
