I disabled FTP and was still able to use a secure FTP (SFTP) program just fine. The options for H.323 and TFTP are off by default. On firmware version 8, the SIP gateway is always enabled and the ones for FTP and IPsec NAT-T are enabled by default. On Peplink routers, these options are in the Advanced tab, in the Service Passthrough section.Here are examples from eight different vendors. Will turning any of these off cause a problem? The only way to know, is to try it. Not only do the names differ, but different routers offer different options. I am no expert on this, but when the ALG/Passthrough options are off, you are safer. Some routers call it Application Layer Gateway (ALG) and other routers call it Passthrough. This is a really annoying topic, starting with the fact that it goes by two different name.See too, Australian businesses targeted in Cisco switch and router attacks from Aug. Granted the story is about a modem, this time. Or, it might be buggy: Several Cable Modem Models Affected by SNMP God Mode Flaw (April 28, 2017). It can be used in an amplified reflection attack, where a small command generates a ton of output. And, even without these issues, no one needs IP version 6, so turning it off lowers your attack surface. Just having IPv6 enabled made you vulnerable. In 2013 someone discovered a bug in IPv6 regarding fragmentation buffer overflow. A great article on this is: Your Wi-Fi router could tell everyone where you live - here's what you can do about it by Paul Wagenseil of Toms Guide. 2023) to 'ensure your router supports IPv6 firewall capabilities.' In August 2021, A presentation at BlackHat showed that a public IPv6 address can sometimes be used to learn your physical location. If the router can not disable IPv6, the NSA recommended (Feb. After turning off IPv6, test that it is really off at. Peplink refers to it as CLI SSH (CLI = Command Line Interface). Here is one example of why SSH should be disabled: Akamai Finds Longtime Security Flaw in 2 Million Devices. See a screen shot of disabling Telnet on a Verizon DSL gateway. An October 2016 study by ESET found that Telnet access was available from the LAN side in more than 20% of the 12,000 routers they tested. In May 2018, it was reported that an ISP in Brazil shipped routers with Telnet enabled and no password. The list was compiled by scanning the Internet for devices that were exposing their Telnet port and making educated guesses. The list included each device's IP address, along with its Telnet username/password. In January 2020, a hacker published a list of Telnet credentials for more than 515,000 devices.

Telnet access to the router on both sides (WAN and LAN).

If so, instead of creating a hole that anyone could walk through, this approach creates a hole that employees of the router manufacturer can walk through. Chances are, they phone home to the router manufacturer rather than opening a port. I am not sure how routers configured with a mobile app handle remote access, there may well be different approaches. If you need Remote Administration, then try to limit it by source IP address or source IP network. Peplink calls is 'Web Admin Access.' Routers with a web interface, require an open port for Remote Administration. It is also commonly called 'Remote Management' and there may be other terms for it, such as 'Web Access' too. This is the function that lets someone on the Internet access the web interface of the router. For more, see the UPnP section of the Security Checklist page. If it does, then you need to make a choice: either live dangerously or setup the necessary port forwarding manually.

Turning these protocols off may break something. Many routers only support UPnP, Apple routers support NAT-PMP and higher end routers support both. UPnP was from Microsoft, NAT-PMP was developed by Apple.

This makes setup of some new devices easier, but is a huge security hole. UPnP and NAT-PMP are two different protocols that do the same thing - they let devices on your network poke holes in the router firewall.Better yet, don't buy a router that supports it. But, if not, turn it off.Įvery router will not have every feature listed below and there will be times when a certain feature can not be disabled. What follows is a list of router features that most people can turn off most of the time. Techies refer to this as reducing the attack surface.

The less software that's running, the safer you are. No doubt, the vendors think people will buy the router with the most features.īut features can be bad. One way that consumer routers compete is on features.
