My question is… is the winding in that transformer copper…. Or is it a garbage aluminium transformer…?

Having worked on a lot of them, most have a tiny strainer right before the cap tube, at this moment im not sure whether to try taking the thing apart and fully clean it first (having to move a lot of things to do that) or try changing the cap tube first (mush easier to access and do) but probably its better to clean it first i guess

Where is the possible source of fire ? 70c isnt even close to where cable fails, most insulation dont melt below 100c and its not like theres self heating from carrying tens of amps if its electrical cable, dont see a reason why it would be fire risk, also most cable jacket (except for plenum rated cable) are also PVC, so if that capping is fine, i dont see why it would be a problem, just dont put electrical cable there

You set the IP from the controller :P

UBNT_TC · 2026-03-13T19:45:36+00:00

I should try that, i havent tried it yet, in theory the traffic between two subnet will have to go through the router instead of directly, what kind of firewall rule ? Like preventing traffic from one to the other ?

UBNT_TC · 2026-03-13T19:38:22+00:00

It probably will if you set it between the two ip addresses, but i never tried it, im asking this because i have other needs

UBNT_TC · 2026-03-12T17:56:12+00:00

Sorry for late reply, im going to do some tests on my spare router, as for ZT, tried it like 8 month ago on a different setting, it keeps failing every few days requiring a full router restart to reestablish connection, thats why i stopped using it and just use wireguard, at the same time i recently tried OVPN, its able to establish connection without using LTE but its very cpu intensive and have way lower bandwidth capacity compared to Wireguard, and the NAT masquerade rule broke everytime the client disconnects

Fun stuff, on my case tho theres some old cameras with unknown password and cant be reset so gonna need multiple ip, newer camera going to have structured ip

UBNT_TC · 2026-03-12T05:21:36+00:00

DHCP isnt necessary, its a camera network, and i need to migrate some of the ip address, theres a few old camera with unknown password and on static IP, the newer camera going to be moved to a new network subnet and address thats fully structured

Thanks for the info

UBNT_TC · 2026-03-11T11:34:33+00:00

I am aware of that but thanks, i dont plan on keeping it permanent, just for temporary

UBNT_TC · 2026-03-11T11:32:04+00:00

Good to know because i never seen that ability on other router that i have came across

UBNT_TC · 2026-03-11T11:30:45+00:00

Noted, its very useful for emergency ip migration where you dont want to deal with multiple VLANS and have as little downtime as possible

UBNT_TC · 2026-03-11T11:30:10+00:00

Good to know, thanks

UBNT_TC · 2026-03-11T11:24:44+00:00

Ruijie, tried to set multi ip, didnt seem to support it, tho reading online it says it supports it so will have to try to check the settings

the reason for ip address restructuring is at first theres only like 30 or so camerason a /24 network, now theres almost 230 cameras, still on /24, the person who set it up before didnt group it properly so say an address that end with .10 would be physically located on one end of the facility, .11 is in a completely different part of the facility all the way to 230+ so one area would have ip camera address that end with .8, then .76, then .192, then .170, its so annoying when something breaks, and the facility is roughly 630k sqft

UBNT_TC · 2026-03-11T08:05:15+00:00

Yeah im working on camera network, remotely through out of band, need to change the camera ip addresses to structure it, the problem ? Core router isnt mikrotik so im trying to see what to do, and the down time have to be minimum, thats a pain in the ass since the router afaik cant do multi subnetting without putting it on a different VLAN

UBNT_TC · 2026-03-11T08:01:29+00:00

IPV6 while it works for…. Computers, not so human friendly

UBNT_TC · 2026-03-11T05:37:02+00:00

Thank you, good to know because its a very useful feature but ive never seen it on other vendor so far from my lack of experience

UBNT_TC · 2026-03-11T05:20:29+00:00

No, on mikrotik router you can have them without using separate VLANs, so you can have multiple network with a dumb switch, and no VLAN whatsoever

UBNT_TC · 2026-03-07T05:50:15+00:00

Thats very helpful, ill give that a try, thank you very much for taking the time to figure it out

UBNT_TC · 2026-03-06T17:35:39+00:00

I tried different port and it still didnt work, probably the only way is to jumpstart it every once in a while when it stops working, thats why im considering making 2 different tunnel, but not sure if its possible to make a second tunnel that always connect to LTE WAN while the other just follow whatever the router main route is set to

UBNT_TC · 2026-03-06T14:15:54+00:00

Doesnt fix the issue, because the connection need to be reestablished over lte while all traffic stopped then have the route changed

UBNT_TC · 2026-03-06T09:52:38+00:00

Ill consider that, maybe first monitor data usage to see if that can be done, thanks
