Description
Steps that could still be done:
- dynamic keying (ISAKMP2), using EAP-SIM (EAP-PEAP also ok, as you don't probably have required keys for EAP-SIM). Strongswan IPSEC supports both ISAKMP and EAP.
- 'handover' with GPRS PDP. IP address is assigned by commercial 3GPP operator for default APN. Then you will setup WLAN connection with IPSEC, where home address will be the same IP as assigned by 3GPP service. You would need to run private application server, which is able to communicate with the device using public internet (3GPP) and when WLAN handover is done, switch the routing to the device thourgh MAG even though the device IP address remains same all the time. Application server is kind of PDN GW
- run all in the N900

This task is technically infeasible:
- if we get real (routable) IP address over PPP, then we cannot have this address on our app server, as it is in its own network, which address we cannot change;
- if we get private IP address over PPP, then we're acting through the NAT with the real address. The latter address is our TCP connection endpoint address, and again, we cannot have this address on our app server;
The only point which is able to do such routing is the real PDN GW of PPP provider.
