ERlite to ERlite ipsec vpn not working when local ip = 'any' - dynamic endpoints

Hi guys,

 

I'm trying to run an ERLite ipsec vpn tunnel to an ERlite tunnel. Both endpoints are DHCP but I use dyndns.

 

endpoint1 = site-1.dyndns.org

endpoint2 = site-2.dyndns.org

 

I can ONLY get the tunnel to come up (ping devices on the other side) when the "Local IP" field has the router's IP. This is fine except that the endpoints are DHCP and could change at some point in the future, which would then destroy the tunnel.

 

Previously, I used a Juniper NS5-GT firewall which was connected to an ERLite router. I had an IPSEC tunnel there and I was able to enter the Juniper's dyndns IP, and then 'any' as the "Local IP" on the ERLite side. Now that both endpoints are ERLite, it's not working any more.

 

It appears that this field will not accept a hostname entry, so I can't put in site-1.dyndns.org, I have to use a numerical IP. Are these devices just simply designed for static IP use?

 

How can I make this work with my dynamic DNS IPs?

Does anyone know how to make this work?

 

Thanks
