Remote access issues

[kaledi 41]

Hello,

I've previously been successfully accessing Emby remotely.  This was with a fibre to the cabinet ISP and I had the ISP router act as a modem and a Linksys Velop system as my router / wifi.

This of course required me to set up port forwarding on the ISP router and again on the Linksys router.

I've just changed ISP and have fibre to the premises, so the only thing that has changed is the ISP router.  I've configured this in the way I believe it should be set, but I can't get it to connect remotely.  For information, I also have a Plex server on the same device, and though I seem to be able to connect, it informs me that I don't have a direct connection and the quality is transcoded to very low bit rate.

The IP set up is as follows

ISP router IP address: 172.16.1.254

Linksys router IP address given by the ISP router 172.16.1.1

Linksys router IP address on the internal network 192.168.1.1

Emby server address (WD PR4100) 192.168.1.11

I port forward 8096 on the ISP router to IP address 172.16.1.1

I port forward 8096 on Linksys router to IP address 192.168.1.11

Any help you could provide?

Hi there, I would suggest checking out our connection troubleshooter:

Please try the steps listed there and let us know which steps succeed and which ones do not. Thanks !

Instead of trying to "configure" the ISP router does it have a bridge mode?  If so, set it to bridge mode and run a single Ethernet cable from it to your Router.

Having a double firewall isn't a bad idea, though. I do that. You just need to forward the port on the front router to the IP of the back router. Then from the back router to the server IP. You just have to remember what you've done if you need to troubleshoot.

But in your case, you need to make sure that your linksys doesn't NAT. That needs to be disabled.

What Carlo is saying by bridging, does make it easier.

Thanks - so the front router can't be put into bridging mode.

If I disable NAT on the linksys, will I encouter issues elswhere?

[sooty234 266]

No, it'll just be a gateway, and your ISP router will take care of NAT. Your linksys will just be at the top of your LAN. Just get familiar with your config, because you'll need to remember how your traffic flows if you need to troubleshoot, and/or use SSL or VPNs. You will have to troubleshoot at some point.

So this is a double nat?  If so you just need to get your forward ips correct.

But still don't know if ISP is a CG-NAT.

I port forward 8096 on the ISP router to IP address 172.16.1.1

I port forward 8096 on Linksys router to IP address 192.168.1.11

But this ip assignment does really make since to me.

That's a great link.

[sooty234 266]

He might need to create a different subnet. I used 10.1.1.1/24. I wonder how much control the linksys will allow?

I followed the instructions.  When I go to the following  canyouseeme.org, it does not successfully connect to the emby port

Why do you say that the IP assignement doesn't really make sense?

I guess it is possible but just doesn't seem write to me.

Who is your ISP?  Do you know if they a CG-NAT?

Have you tried connecting Emby directly to your ISP router and port forwarded?

[sooty234 266]

Change your linksys to 10.0.0.1/24, then reboot your server machine and ISP router, with the linksys still powered up.

He's got fiber to his house. If it's CG-NAT, I would be horrified.

[kaledi 41]

thanks, but I still don't follow?  What would that IP address not seem right?  I set the ISP router to have the IP range 176.16.1.1 to .254 to avoid conflicts with with Linksys that uses 192.168.1.xx range.

I'd really prefer not to change my linksys range from 192.168.1.xx as I have many devices that have reserved IP addresses.  I can change the ISP router IP range though

Those networks can not conflict.  But if you are reassigning IPs the I guess .1 could be provided to something else as it should be the ISP router IP.

Oh, I see, yes.  If I understand you correctly, you're surprised that the ISP router IP address isn't 176.16.1.1 .  I was too as the router default is .254, and I did not change it.

[kaledi 41]

Should set my linksys to use NAT or RIP?

[sooty234 266]

Mine are configured:

(internet) WAN  -->  (router #1) 192.168.1.1 -->  (router #2 WAN) 192.168.1.195  -->  10.1.1.1/24

@kaledi if you want another set of eyes to look at your setup send me a PM and we can setup a remote support session and I can give you a hand.

Carlo

[kaledi 41]

@cayars thank you for the offer, which I'll gladly take up.  Will PM you now

[Carlo 4561]

Just noticed your WAN IP is 172.16.1.254

172.16.0.0/12 is non-routable meaning YOU ARE in a CG-NAT type situation or similar and you won't be able to setup Emby on the Internet via port routing AS IS.

Who is your ISP?

This within the routers (1) DHCP pool, not the WAN address.
