Internal IP redirect to public IP (Linux)

[FlorinMarian 144]

Hi guys !

Anyone managed iptables rules or something similar to stop kicking character after selecting character in that situation when Metin2 server runs behind a internal ip ?(separate VPS)

best regards.

You need to modify your server sources to get public io instead the private one.

40k files not support NAT buongiorno default, but with sources you can do everything.

desc_client.cpp in void CLIENT_DESC::SetPhase(int iPhase) edit

				if (!bSentBoot)
				{
					bSentBoot = true;
					TPacketGDBoot p;
					p.dwItemIDRange[0] = 0;
					p.dwItemIDRange[1] = 0;
					memcpy(p.szIP, g_szPublicIP, 16); // set you external ip instead g_szPublicIP 
					DBPacket(HEADER_GD_BOOT, 0, &p, sizeof(p));
				}

or you can do it in client side at NetAddress.cpp

void CNetworkAddress::GetIP(char* szIP, int len)
{
	BYTE IPs[4];
	*((DWORD*)IPs)=m_sockAddrIn.sin_addr.s_addr;

	_snprintf(szIP, len, "%d.%d.%d.%d", IPs[0], IPs[1], IPs[2], IPs[3]); // replace with you external server ip
}

Thank you very much but in this way doesn't work because cannot bind on this IP.

Try using forwarding

You dont need to bind port on external ip, youmust still use you internal ip.

I also want to know, who can change this function?
