I have a site to site VPN up and running, if you check the PDM or command line it shows the tunnel up and established. This all worked fine until yesterday and now even though the tunnel is up no traffic is going through. I can not ping or access anything on the other side of the tunnel and vice versa.
I have reloaded both devices as well as the cable modem on this end and the DSL modem on the other end.
Any ideas what to do next? Is this possibly an ISP thing?
Thanks for any help!
