[Solved] DASAN H640GW Admin Panel Login: Access Router Admin Panel with Root/Vertex25 Credentials

Hello,
Friends how to get to the administrative panel of the router?
router after reset and at the address http://192.168.1.100:8080 user / user I can manage what isp allocated,
I know root / vertex25 is admin data, but at what address? because above it pops up that not hijacked login. I reset the router with the button until alm stops flashing and clears user settings. I am asking because my ISP has a lot of me ** when I have a problem with NAS,
I can't log in to it using the address (ip) when I'm at WAN (i.e. at home), but there is no problem with the network. The routing table is a shit in Chinese crap, because at another ISP and on your own router there was no problem. The exact problem is that I have a fixed IP, enter them at work and log in to the NAS without a problem, but only 192.168.1.1 works at home because the global one will not log in. Nat replikation or other system would solve the problem but dasan has such a poor menu that every netgear eats it to start

If after reset dasan has the same configuration it is because it gets it from olta. You must call the provider to make your device router.

and everything is clear, thank you for rep

the router gets settings from OLT, I can't change the settings
