Since you were the only expert to respond I'll give you the points but actually the Telco caused the problem. as soon as they raised the Mtu everything started working again. Thanks for trying.

Thanks rettif9, glad you got it working.<br />
<br />
We could also have adjusted the MTU on the tunnel to overcome the telecom settings.

Gateway to Gateway VPN<br />
<br />
RV 180w on both ends<br />
<br />
This VPN was working till one location experienced a power outage over the weekend. Both locations have Internet access but can't connect VPN.<br />
<br />
I checked all VPN settings to make sure nothing had changed in either router, WAN Static IP is still the same on both ends. Next I upgraded firmware to v. 1.0.4.14 on both ends, deleted existing settings in both routers and used the &quot;Basic VPN Setup&quot; option. Same problem - IPsec SA Not Established. I have searched for a VPN log in the menu but haven't found it.

A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.
