Can't add routes to iPad routing table

[chris.tucker@bourne-leisure.co.uk]

I'm testing OpenVPN client v1.01 on iPads. If the clients are on a test wireless network (using a 192.168.x.0/24 subnet), all works as expected, so I'm sure that our configuration is working correctly. However, the clients will have to work on a live wireless network (provided by Arqiva) which issues DHCP addresses in the 10.0.0.0/8 range. Our corporate network also uses the 10.0.0.0/8 subnet, so we have a routing issue. A workaround which has been successful on Windows clients is to push two routes to the clients from the OpenVPN server, (push "route 10.128.0.0 255.128.0.0" and
push "route 10.0.0.0 255.128.0.0"). Once these routes are added to the client routing table, the clients can connect to our 10.x.x.x servers, since they always match one of the /9 routes over the VPN in preference to the /8 route over the local subnet. Although I can see in the client logs that the routes are being received from the server, the IT Tools app shows that they are not being inserted in the routing table and the client cannot connect to 10.x.x.x corporate servers. Can anyone please point out what I'm doing wrong and/or suggest what I should try next?
