That's really weird. Here, let me show you the code :-
l_LocalInfo.sin_addr.s_addr = GetHostAddress (m_Peer.LocalIP()); //
This is where the local IP is used l_LocalInfo.sin_port =
l_LocalInfo.sin_family = AF_INET;
m_PeerInfo.sin_addr.s_addr = GetHostAddress (m_Peer.PeerIP());
m_PeerInfo.sin_port = m_Peer.PeerPort();
m_PeerInfo.sin_family = AF_INET;
if ((m_Socket = socket (AF_INET, SOCK_DGRAM, 0)) == SOCKET_ERROR) //
Fail if we can't make the socket
DbgPrint ("[%s] can't create UDP socket\n", Name().c_str());
else if (bind (m_Socket, (LPSOCKADDR) &l_LocalInfo, sizeof (struct
sockaddr_in))) // Fail if we can't bind the socket
DbgPrint ("[%s] Can't bind to port [%d]\n", ntohs
This is the only place that this address is used in the program. If you are
entering a Local IP that neither matches any of the IP addresses bound to
working network adapters or 0.0.0.0 and it's crashing then it's going to be
Winsock 2 that's complaining.
However, tcpip should not even be accepting packets that aren't directed to
bound IP addresses. If you are using ipchains, then you also need to use
ipmasqadm. This allows you to setup reverse masquerading on specified udp
and tcp ports. I use this myself on a (Linux based) CIPE WAN going across
masquerading (Linux based) firewalls.
