R6200 - How to unblock IP addresses

Hi,
I am trying to unblock specific IP addresses that are requested in order for my Verizon Network Extender to work. I think I've successfully port forwarded the specific VPN ports that they require to be opened but I don't know how to add a specific ip address. Everything I read says go into the firewall settings under security but my router does not have that option in the manual? Can anyone help as this seems to be a critical piece to get my network extender to work. Thank you.

Re: R6200 - How to unblock IP addresses

I think Verizon is jerking your chain - have they told which in "direction" the port needs to be opened? If not ask them. By default, all outgoing traffic is permitted and all incoming traffic is blocked, unless the incoming traffic corresponds to a prior outgoing request. Port forwarding is only required if you want to permit an unsolicited incoming connection. I suspect the instructions you have been given (open port xyz ect.) are intended for use with corporate firewalls, which are configured differently to consumer firewalls, and whilst the network extender does require these ports opened - in your case they are most likely already open, they were never closed.

you may be right. This was taken from their website for installation and troubleshooting instructions for the network extender.

The following ports and IP addresses must be unblocked for the Network Extender to work properly.

Ports:

TCP
53
52428
UDP
500
4500
52428

Re: R6200 - How to unblock IP addresses

The critical information is what direction - inbound or outbound.

I should have included the first paragraph, it appears both...

It is necessary to enable Transmission Control Protocol (TCP) and User Datagram Protocol (UDP) (incoming and outgoing) for specific ports and/or unblock specific IP addresses on the modem/router. Refer to the Internet Service Provider (ISP), Network Administrator, or equipment manufacturer for assistance with these settings. Examples of router setup are provided here; however, Verizon Wireless doesn't support 3rd party routers.

I have the same problem with an ATT Microcell.  The manual for my Netgear R6220 says all incoming ports are blocked by default.

Hi @MoonValley,

 

Have tried performing port forwarding for the Microcell device? If not, then you may refer to the link below for the steps. Also, you will be needing the specific port numbers that AT&T requires to be opened for the Microcell.

Re: R6200 - How to unblock IP addresses

The following are the settings required by ATT:

-DHCP is on

-Data is not restricted from passing through ports 4500 and 500 (AKA Port Blocking).

 -MTU size is set to 1492

-MAC address filtering is either turned off or allowing the MAC address of the AT&T MicroCell IPSec Pass-Through is Enabled

-Block Fragmented Packets is Disabled

-If the MicroCell is connected to a router that is connected to a modem and both the router and the modem have NAT (Network Address Translation) enabled, disable NAT either in the router or the modem.

-Ensure the modem / router is using the latest software (firmware). Please see the manufacturer's documentation.

-TCP/UDP Ports

Note: All ports listed need to be configured for inbound and outbound connections.

-123/UDP: NTP timing (NTP traffic).

-443/TCP: Https over TLS/SSL for provisioning and management traffic.

-4500/UDP: IPSec NAT Traversal (for all signaling, data, voice traffic).

-500/UDP: IPSec Phase 1 prior to NAT detection (after NAT detection, 4500/UDP is used).

-4500/UDP: After NAT detection, 4500/UDP is used

 

The port forwarding custom service has the following port ranges set for external and internal.  Protocol for all ports is set to TCP/UDP.

123-123,443-443,500-500,4500-4500

123-123,443-443,500-500,4500-4500

 

 I have set the MTU size to 1492, enabled IPSec pass-through, and set NAT to "OPEN".

There are no entries listed in Port Blocking.

Hi @MoonValley,

 

Have you tried by passing the router and connecting the Microcell straight to the modem and see if it works from there?

Re: R6200 - How to unblock IP addresses

I took the router out of the loop and connected directly to the cable modem.  The result was exactly the same, so it seems pretty clear that the router is not the issue.  I will circle back with ATT and post here when I have news.
