Hello Experts,
I need some help setting up a VPN on my RV042. I am going to have multiple remote offices with laptops that go from office to office. At my remote location they will have cable modem with a dynamic IP and a RV042. But my main office has a RV042 with a static IP.  I need some advice of the config and ip addressing.

I don't think the RV042 supports true dynamic IP for its VPN tunnels. I have an RV042 at home and the tunnels depend upon my home ISP IP not changing much. It doesn't so there has been no problem. I can think of two approaches:
1. My appproach above, and be prepared for the odd change. Dynamic IP's usually don't change that much.
2. Use a product like DynDNS at the remote locations to create a static IP for these locations.

Yes, you should be able to set this up, as long as one end is static.

Check the SIte for VPN between Static site and Dynamic site.

IT is simply a matter of setting the phase 1 or 2 to be aggressive.

I hope this helps !

regarding aggressive mode.

You should not need to use a Dynamic DNS service, but you can if you want.

I had this working for a while before switching to netscreen NS 5 GT firewalls.

You can set it up with one end static but the other end (I think) will change if its IP changes, which is what I was referring to. The asker already has one end static. I have my own RV042 (dynamic IP) connected up to several NS 5GT's but it needs to know my home IP.

NS GT's on the other hand can have one end dynamic and the tunnel will remake itself if the dynamic end changes. ... Thinkpads_User
