Hello all,

Im having an isec tunnel to a provider were we get some IPs for our UMTS devices. The umts devices having Internet access but no accces to orange zone. Also from orange zone to ipsec tunnel. I can not ping the umts devices.
I looked to google, but can not find any information having access between orange and ipsec.
I tried also routing and firewall settings with no luck.

Whats wrong?
Can someone help?
