I just installed a Cisco 851 Router. I have everything working pretty well EXCEPT I am unable to complete a VPN Connection outbound nor can we VPN inbound. The outbound connections are from Windows XP PCs using the built in Microsoft software. I can connect to the other server (different domain 10 miles down the road) and input username and password and then it just sits there. I believe this involves GRE pass-through but I can not figure out how to configure. Nor can we get VPN incoming to our server. I have port 1728 port forwarding but again I think GRE is rearing its ugly head.
Worked great on my Linksys router.
Does anyone have any ideas? This is my first exposure to Cisco products.
I shouldn't need a key for both ends of the VPN. I am merely trying to connect to various customer VPNS that terminate to their router or to their servers. I am using statdard Windows VPN applet for this.
I am not trying to create a site to site firewall with the routers connecting to each other.
My traffic is being allowed outbound and then blocked inbound. There is obviously another port I need to allow inbound or else something I need to do in my firewall configuration.
I looked at easyVPN and that seems to be for use with the Cisco VPN client. We were using pass-through VPN on our previous setup with direct connection to the Remote Access Server built into Windows server.
A little background:
We have a cable modem on a Cisco 851
I am using SDM to configure as I do not know IOS commands. I basically used the wizards with some customization of the NAT rules.
I barely know what a cryptomap or transform is. I am hoping to find a good book on this, but so far have failed.
Thank you for trying to help. I appreciate all help.
