Hi All, I need technicial assistance with either a routing or ip restrication problem impacting our mobile ip customers in Australia. Customers using our Mobile Network are allocated an address in the 1.128.0.0 - 1.159.255.255 range to allow communication on the internet. I have a customer's who can't reach websites hosted oversea where the like cause appears to be some were in the Level 3 routing domain (I suspect). 1. Customer A trying to get www.readingeggs.com.au fails when using a Mobile Internet connection.

It appears the path is being treated differently between routers: ae-22-70.car2.SanJose1.Level3.net [4.69.152.68] & ae-42-90.car2.SanJose1.Level3.net [4.69.152.196] from the Telstra Global Router. I am looking for network help and confirmation that the source network 1.128.0.0 - 1.159.255.255 is being routed correctly back to Telstra's network in Australia correctly on the SanJose - Level3 routers. Also check if any bogan filtering is in the network that could be blocking the source ranges from reaching the hosting URL. Regards, Attila Vekas Telstra
