I know I did this before, but it still didn’t work after working for a while. I think if you keep reloading the plex page, or keep clicking “apply” for the manual port (which causes it to reload) it eventually gives you the error again that it isn’t available outside the network.
However, it seems to be stable for now… The system logs still show a possible DNS-rebind attack warning but I guess it’s OK for now, fingers crossed!
Hello, I am having the same issue with this router. Any solutions? Above did not seem to work.
So far the only solution that seems to work is setting the dns server to something other than VZ. I changed on my server and the router
Not the worst solution. 
Bump, nothing is working. I’m about to buy a new router, but has anyone else resolved this?
Still working out some issues on this thread: Remote access not stable... Verizon Fios g3100 router problems?
Although I’m going to call Verizon tomorrow and get a straight answer because this crazy. I did the manual port, I changed the DNS server, I followed a bunch of other steps–nothing. The worst part is the server is up sometimes, and down other times. There doesn’t seem to be a rhyme or reason about it. It’s always working from anywhere on the router, but as soon as it’s an outside connection? There’s a 50/50 chance the server is going to be up and let you actually access anything.
I am in the same situation - If I refresh my Plex server to reconnect the remote access it will allow me to connect outside the network for a few minutes, but usually within 5 minutes it will close off access once again until I come back on the admin side and refresh it again
following for the same thing. did anyone ever call verizon?
I’m having the same issue like most people in here. I usually have a few friends jumping on my PMS to watch a few movies, but it seems like they can’t go through a movie without PMS dropping remote access. Is this a router or software issue?
I have the same issue when I try to establish multiple Plex servers on the G3100 Router. My movie server works fine while using the port forwarded to default 32400. I have port forwarding setup for my Plex TV server on port 324xx. Each time I designate a new port, the server enables remote then disconnects a minute later. No amount of retrying the port gives me a stable connection. My movie server on 32400 remains stable. Is this really just a problem with that Router?
The only solution I know of to have more than 1 Plex server work remotely accessed on a network is to put a “Managed” switch after your router. You would need to set up the switch so that port 32400 is forwarded to a specific VLAN and have only your Plex server(s) on that VLAN. I have a friend from work that has done this and it does work. I’m not sure what brand/model switch he is using or the $$$.
Absolutely not true.
All you need to do is to define port forwardings in your router, so that each plex server in your internal network has a different public/external port number.
Whether the router model discussed in here allows this, is unfortunately not known to me.
There is always the option to use a different router or use an alternative firmware, which allows this kind of thing.
For those still looking for a solution, you can disable DNS Rebind in the router by going to Advanced > DNS Server and unchecking the Stop DNS Rebind checkbox. This seems to be working for me so far.
Does this create a security issue for your network?
