I am having an issue bringing up a VPN succesfully between two remote locations. This is a site-to-site VPN and I've attached the physical layout. Now I can confirm to you that that VPN comes up, Both show ass MM_Active and both show sending and receiving data. I can also ping across the VPN however I cannot send any data over at all. I get SYN Timouts. So basically one side is just an ASA however the other side is an ASA attached to a 6500 running multiple contxt FWSM's. However for this all we are really conceren with is just one FWSM which I have layed out in the diagram.
Just to reiterate the Tunnel does come up and pings to work however if I try to telnet or open a web browser betwen the tunnel I get SYN Timeouts. This could be because of asymetric routing and if so can you advise on how I could resolve this. I know for a fact the issue is on the left side of this diagram with the ASA and FWSM and 6500, I just don't know he to forego the asymetric routing or use another solution so I can get this to work fully. Thank You for all your help in advance!
