Hello,we are looking to get SDSL service from MegaPath at one of our locations and wish to use our standard hardware (Cisco 1720 / Cisco Cat1912). Can anyone recommend what hardware we could use to connect the SDSL side to the Cisco 1720? I would p...
Hello,we are currently running a VPN through the internet using IPSec tunnels (no GRE/IPSec yet). At our main office, we have a C3640 with one internet T1 and 30 tunnels to remote locations (static IPsec). Now, we are going to add a VPN 3000 series...
Hello,we are currently connecting our main and remote offices together with a mix of Cisco routers (3540, 2600s, 1720s) using IPSec tunnels and access-lists on the serial interfaces to only allow the serial IPs of the other routers in (the encapsulat...

Thanks for the reply. To test to make sure that either the cyrpto df-bit clear command or the route-map is working, can a ping -f -l3500 [hostname] from a windows machine work as a test? Is there another method?Thanks.
Thank you for the response. Is this the only plus to using the loopback interface (that it and the tunnel will not go down?). Each router I am working with has only one internet connection through the serial interface and 34 tunnel interfaces (35 t...
