So I had a play and cant get a zyxel accessible from a remote IP at all myself.

I'm thinking its probably due to a modem mode zyxel not having a default gateway etc, no access to outside of the lan.

Will fiddle more tomorrow.

Thanks bud, setting up wireguard for now though.

Will find a more optimal solution to occasional remote access to the modem, but having a wireguard setup to remote into your network from any location is never a bad thing!

That is very true, however thank you for your time and assistance. Will let you get back to what you was doing.

Update: I tried Wireguard and although I could pull up the router WebGUI I couldn't pull up the modem WebGUI so really stumped.

Sincerest apology if you know all this already: Being in the same IP address range doesn’t mean you’re automatically in the same subnet - definition = “broadcast domain”. In my case the main LAN broadcast domain has an 81.187.x.y public/global/routable address in a /26 and each modem’s admin i/f lives in its own broadcast domain at 192.168.n.1 where n=1,2,3,4 is the nth modem (I have four modems). So that’s 1+4=5 broadcast domains=5 subsets, and in my case they are all distinct non-overlapping address ranges, but that’s just coincidental, it’s down to how I configured the modems.

It's always a great thing to relearn so no need to apologise beside it might help others.

However both modem and router are in same ip range of 192.168.1.0/32 I have even tried 192.168.1.0/24 however It did just remind me my Guest network has been setup on another range with firewall rules set to block WebGUI access and that's on the same vlan going to wan.

I don’t understand your comment about "/32". That’s not large enough to have two IP addresses in it. Surely the modem and the router have to have two distinct IP addresses in their subnet? How does the modem manage if an incoming packet has src_address==dest_address, as when it replies to incoming packets it will be replying to itself? So I don’t see how the modem can be in a subnet that is /32. Your main LAN will typically be in a /24 or /16 if it’s in the usual home user setup with RFC1918 NAT-ed IP addresses?

Each of my modems lives in its own /24, as it happens, and in each subnet the modem is 192.168.n.1 and the router is 192.168.n.254.

[hacktrix2006]

I have Modem on 192.168.1.1 /255.255.255.0 and router on 192.168.1.3 /255.255.255.0 with guest network on 10.0.1.1 / 255.255.0.0 .

Guest network and normal network are on same vlan however guest network is isolated from the main network via firewall rules so they can't access webgui's or main network systems.

Hopefully this helps clear things up.

Right. Some confusion earlier then, as you have a /24 there given it is 255.255.255.0, not a /32.

[hacktrix2006]

Sorry about that networking can be confusing at times lol. Hold up I had wireguard setup up to /32 and not /24 so that might be why it didn't work with wireguard lol. Will mess again later thanks for your time.

Question: on the CRC and FEC const vs time graphs, what are the units on the verticaly axis? I have modem #4 running very very slowly, with a lot of noise and the downstream CRC count is high compared to the other modems. The CRC rate figure shown on the y axis is the count CRC of corrected errors[?] per unit what time[?]

It is a still a new performance nightmare at the moment. The downstream SNRM was 2.5 dB and I forced a resync which brought the d/s SNRM up to 3.1dB. The downstream rate is even slower now, with a downstream sync rate below 2.5Mbps, whereas it was  ~2.9 Mbps before, and in total I have lost about 0.8-1.0Mbps total effective download rate from speed tests with speedtester2.aa.net.uk compared to what it was like a couple of months ago.

Live sync rates:
  #1: down 2807 kbps, up 519 kbps
  #2: down 2700 kbps, up 544 kbps
  #3: down 2964 kbps, up 389 kbps

Question: on the CRC and FEC const vs time graphs, what are the units on the vertical yaxis?

Number of events per minute. I.e. number of CRCs per minute and number of FECs per minute.

The CRC rate figure shown on the y axis is the count CRC of corrected errors[?] per unit what time[?]

No, not corrected errors but actual CRC errors recorded in the immediate, preceding minute.

[Weaver]

Thank you I take it that FEC count is the count of error events corrected by RS ?

So it’s per minute. Where does L2 RETX come in in this count? Is PHY irrelevant here, if retransmission is required then it goes ahead and either succeeds or not but isn’t shown in these particular figures in this graph?

In the raw stats figures, are those first numbers under bearer 0 etc : ReXMT etc - are those just cumulative totals? Those in the first set just up and up? As opposed to being counts per some unit time interval? Which one sees further down in the various time interval sections.

Yes, RS and any other "goodness" that was capable of making the correction

Sorry, that is something I do not know.

They are cumulative totals. The delta is created by subtracting the previous cumulative total (at time n - 1 minutes) from the current cumulative total (at time n minutes).
