Enabling IP forwarding

[tsdgeos]

Hi, is it possible to enable IP forwarding in Symbian phones?

It seems PIPS defines IPCTL_FORWARDING so you could do the typical

int mib[4];
int state = 1;
mib[0] = CTL_NET;
mib[1] = PF_INET;
mib[2] = IPPROTO_IP;
mib[3] = IPCTL_FORWARDING;
sysctl(mib, 4, NULL, 0, (void*)&state, sizeof(state))

But sysctl is not defined.

Also i found KSoInetIfQuerySetRouter in in_sock.h but

RSocketServ ss;
ss.Connect();
TPckgBuf<TSoInetIfQuery> buff;
RSocket ipSocket;
ipSocket.Open(ss, KAfInet, KSockStream, KProtocolInetTcp);
ipSocket.SetOpt(KSoInetIfQuerySetRouter,KSolInetIfQuery,buff);

Fails with a -1 (not much explanation) maybe i've to fill some fields of the TSoInetIfQuery but couldn't find any that made sense.

Any ideas?

For the record, i've been have to get the KSoInetIfQuerySetRouter SetOpt call to return KErrNone setting a correct interface name in buff, but still does not make the phone fordward ip packages :-/
