VPN's

We're setting up a VPN solution to one of our satellite offices in another town. The modem they are using is a Cisco 675. Our firewall is a netgear. When we tested out the VPN software here, using the netgear firewall, it worked AOK. We installed the firewall with the Cisco 675, and no dice.

Here's what happens. In order to set up a security association with the firewall here, we have to give our firewall the IP address of the VPN equipment at the other location. That would be the netgear firewall. Soooo.... the Cisco 675 modem must be used in Bridging mode VS. routing mode. If the 675 is in routing mode, it becomes the equipment with the IP address, and then the VPN will not work with the netgear firewall. However... the 675 does not want to pass packets to the firewall when it is in bridging mode. We've checked out everything in the downloaded manual about configuring the 675, but cannot find anything that will solve this issue.

Any ideas?

thanks!

What about NAT??

 

I'm not sure about the NAT - I seem to remember when we first discussed having the VPN that my boss mentioned something about the NAT router not working with the firewall at our end. That may have changed since then - I know for a fact we installed a new firewall last month.

I'll mention it to him, and see if he wants to attempt it.

 

Hmmmmm...I did notice here....

Cisco End of Life Announcement

...that it seems they no longer support these products...also noticed their website sucks. Maybe try to talk your boss into getting a new Router for the office, one that can enable PPTP pass through. Does the Cisco 675 support that? I can't seem to find a manual on the thing anywhere on Cisco's website.

 

Actually, the link you gave me to cisco's site did produce the manuals and service updates that I needed. It just took a little searching to find them. BTW, that site is the old documentation site - and will be shut down soon. I discovered that bridging does not work with PPP in any CBOS (cisco broadband operating system) before version 2.3. Unfortunately, I was unable to find the CBOS updates at the Cisco site, and thought all was lost. I went to the website for the company that provides our DSL connection ( local phone company, Qwest communications) and lo and behold, there was the most recent CBOS update! I've downloaded the update and printed out the instructions for updating the modem. I will go down next week and update the CBOS and then set up our VPN. Woohoo! Thanks so much, you made me look really smart today

Great. Hopefully it will solve your VPN problems! VPN's can be pretty confusing sometimes to set up.
