Hi All,
I have a an issue which i think/hope is an easy one but i cannot see it. hopefully i am missing something obvious:
A device (music player: 10.1.47.251) in a remote site is not responding to ping from our head office.
the device responds ok from the router and from within the remote lan
if i try and ping from the local router to the device and set the source as Dialer0 (internet) the ping fails
If i try and ping the device from head office it fails
If i try and ping 10.1.47.250 (a pc in same remote lan connected to same switch) from head office it responds ok
I have connected the music device directly to the router and to the switch but behaviour is the same no matter which device it is connected to.
Head office lan 192.168.100/24
remote site lan 10.1.47.0/24

Hi Jawad,
Thanks for your response. Unfourtunately i do not think this is the issue.
Access-list 103 is an acl for a VPN to a third party support partner. It is not related to Head Office traffic.
Access-list 102 is the access list for the VPN from Head Office to remote site and is the acl of interest here.
Access-list 102 is configured correctly and this is borne out by the fact i can ping 10.1.47.250 (but not 251)
thanks again
