Verizon Fios Port Forwarding for Game Servers (CR1000A, G3100)

On a Verizon Fios router you forward game server ports from the browser admin page at 192.168.1.1 (or mynetworksettings.com). Sign in with the admin password from the router's sticker, open Advanced, find Port Forwarding (under Network Settings on the CR1000A, under Security & Firewall on the G3100), and add a rule for your server PC's local IP with the game's port and protocol. Reserve that PC's IP first so the rule keeps working after reboots.

Which Fios router do you have

Verizon has shipped a few generations, and the menus moved between them:

Router	Where port forwarding lives
Verizon Router CR1000A (current)	Advanced, then Network Settings, then Port Forwarding
Fios Router G3100	Advanced, then Security & Firewall, then Port Forwarding
Older G1100 / Quantum Gateway	Advanced, then Security & Firewall, then Port Forwarding

The model name is printed on the sticker on the router, along with the admin password. The admin password is not the Wi-Fi password.

Step 1: Find the server PC's local IP

On the server PC open Command Prompt and run:

ipconfig

Note the IPv4 Address, for example 192.168.1.155. On Linux use hostname -I.

Step 2: Reserve that address

Fios routers give out addresses by DHCP. Reserve the server's address so it does not change:

Sign in to 192.168.1.1.
Open Advanced, then Network Settings (CR1000A) or My Network, then Network Connections (G3100). The exact label varies by firmware.
Look for DHCP Reservation or the device list where you can set an address as static for that device.
Pick the server PC and save.

If you skip this, the next power cut can hand your PC a different address, and the rule ends up pointing at a phone or a TV box.

Step 3: Create the port forwarding rule

Go to the port forwarding page for your model from the table above.
Choose Custom Ports or Add. Fios has presets for some applications, but game servers rarely match them.
Device / Fwd to Addr: select your server PC or type its local IP.
Source port: leave as Any.
Destination port: the game's port or range, for example 2456-2457.
Forward to port: the same as destination for a game server, or leave it on Same as incoming port.
Protocol: TCP, UDP or Both.
Click Add or Apply.

The new rule appears in the list below the form. Some ports you might need:

Game	Ports	Protocol
Valheim	2456 to 2457	UDP
Satisfactory	7777 UDP and TCP, 8888 TCP	Both
Counter-Strike 2	27015	UDP and TCP
DayZ	2302 to 2305, 27016	UDP

Step 4: Check the firewall level

Fios routers have a firewall security setting under Security & Firewall, usually Low, Typical or Maximum. On Maximum, inbound traffic is restricted more tightly and some rules behave unexpectedly. Typical is the default and works with port forwarding. If you or a previous owner changed it, set it back to Typical and test again.

Also check the PC side. Windows Defender Firewall blocks inbound traffic for programs you have not allowed. Our Windows Firewall guide shows how to add a proper rule.

Ports Verizon keeps for itself

Fios routers reserve a few ports for remote management and for Fios TV set top boxes. If you try to forward a port in a range the router is using, it will refuse or the rule will silently fail. Normal game ports are not affected. If you changed a game to an unusual port and the router rejects it, pick a different one.

Step 5: Give friends your public address

Open Network Settings or the main status page on the router to see the WAN or Broadband IPv4 address. It should match what a "what is my IP" search shows. Fios gives each home a public IPv4, so there is no carrier NAT to worry about. The address is dynamic, though it tends to stay the same for long periods. A DDNS hostname saves you from resending it when it changes.

Testing it properly

Start the server before testing. A port with nothing listening looks closed.
Test from outside the house. Connecting to your own public IP from inside often fails on home routers even when everything is correct.
For UDP games, a real client joining is the only reliable test. Read how to test if a UDP port is open for tools that help.

Your own router behind Fios

If you plugged a mesh kit or gaming router into the Verizon router, you have two layers of NAT. Most Fios connections give a public address by DHCP over the Ethernet cable from the ONT, so the cleanest fix is to connect your own router directly to the ONT and retire the Verizon router (keeping it if you need it for Fios TV guide data). Otherwise you forward on both routers. The double NAT guide has both routes.

Verizon 5G Home is a different story

The Verizon 5G Home and LTE Home gateways look similar in the app, but those connections use carrier grade NAT. A rule on the router cannot open anything to the internet. See game servers on 5G home internet for what works there.

A moment from Satisfactory

Or host it outside the house

If you would rather not keep a PC on and a router configured, a GamezServers server has its own address and its ports already open. It is live about a minute after checkout, you get one click backups and a live console in the panel, and friends can each pay their share of the bill.

FAQ

What is the Verizon router admin password?

It is printed on the router's sticker as the admin password. If someone changed it and nobody remembers, a factory reset brings back the sticker password, but wipes your Wi-Fi settings too.

Can I forward ports in the My Verizon app?

The app covers Wi-Fi names, device lists and some basics. For port forwarding and reservations, the browser page at 192.168.1.1 has every option and is the reliable route.

Why does my Fios port forward show as closed?

Usually the game server was not running at the time, the protocol is wrong, or Windows Firewall is blocking it. Online checkers also cannot see UDP ports properly.

Is DMZ a good idea for a game server?

DMZ sends every port to one PC, which exposes far more than the game needs. Forward only the game's ports instead.
