Hi,

it could be that the specific server you mention has a route to 10.0.25.0/30 but not to 10.10.1.0/24. This could explain why you can ping the specific server from the remote router but not from the PC as the source address of the ping would be the 10.0.25.1 address. To test this try a ping to the server from the remote router using the 10.10.1.2 as source address.

I don't understand why you can not ping the PC from the remote router .. beats me

HTH, Thomas
