Severum Posted September 30, 2019 Posted September 30, 2019 Hello, So I recently moved to an apartment where the internet is included in the rent. I had zero issues hosting servers at my old apartment where I had both a modem and a router provided by the ISP. Here the modem is built into the wall however I am using the same router as I was prior. Same network name and password. All ports are open. Nothing on the PC has changed. DCS is allowed through the firewall and through my anti-virus. What gives? Any ideas, or suggestions on how to fix this? Rather not have to pay for a dedicated server to host practices for my team.

Rudel_chw Posted October 1, 2019 Posted October 1, 2019 Dcs wont work behind two routers in series, ask the isp to disable the routing functions of their modem, turning it into a transparent bridge, thus leaving your own router as the only router of your home.

That's not how networking works. Firstly, you're making the assumption that the modem is a "router" or NAT gateway. If it isn't, it's probably not an issue. If it is, so be it. While double NAT is ugly in nearly every case, it's not insurmountable, and the local application (particularly network applications like this) will be generally oblivious to it if you have appropriately configured both NAT devices. The key is to configure both NAT devices. On the other hand, there's not even enough information here to know if the user is actually being assigned a globally routed address on the outside of his router. As is becoming more common in these included services, if he's only being issued an RFC1918 address, it'd have to be coordinated with his upstream.

Being said, I cant give that information as I wouldnt know. I'm more or less trying to figure out how to fix this issue. If both devices need to be configured, how do I go about doing that?

Yeti42 Posted October 1, 2019 Posted October 1, 2019 First order of battle would be to figure out which modem/router is assigning your IP address presuming you are using DHCP... open a command prompt and type ipconfig /all and look for DHCP server, if the address for the DHCP server is that of your router then you know that your router is handling it (It probably is as you as the network SSID and password is the same). Open your routers config page and ensure 10308, on TCP and UDP is open and forwarded. To open the router page go to the IP address of the DHCP server and enter the username and password for the router (can't help you with that bit). Also look at the DCS server logs, that should tell you something....

Rudel_chw Posted October 1, 2019 Posted October 1, 2019 That's not how networking works. Firstly, you're making the assumption that the modem is a "router" or NAT gateway. Yes, it was an educated guess :) While double NAT is ugly in nearly every case, it's not insurmountable ... The key is to configure both NAT devices. Almost every ISP is not happy with the user modifying the configuration of their equipment, that's why I suggested that the OP contacts the ISP to get them to disable the routing functions of their Modem, this would cleanly eliminate the double NAT. On the other hand, there's not even enough information here to know if the user is actually being assigned a globally routed address on the outside of his router. As is becoming more common in these included services, if he's only being issued an RFC1918 address, it'd have to be coordinated with his upstream. Why use such dense language? "private IP address" is much clearer than "RFC1918 address" ... we must strive to help people, not confuse them. ... If both devices need to be configured, how do I go about doing that? I assume that you already know how to configure your own router, since it was working fine at your previous home. I've been on the same situation as you, and my soluction was to contact the ISP, tell them that I have my own router and then ask them to disable the routing functions of their equipment (thus turning it onto a bridge).
