[beriv 0]

Hy I had a problem my Dahua IPC-HFW4300S-V2, I reflashd firmware and not work correctly my cam.

First problem is not work ipv4 login I saw ipv4 192.168.0.18, ipv6 login work fe80.....

I'm not saw ipv4 service telnet ssh etc..23,443,3800 with port scanner.

Second problem is I think not good the firmware in my cam, this is the reaseon while not work, but as long as it doesnt work ipv4, I dont know what to do next.

I tried PuTTy ipv6 connect (fe80::4e11:bfff:fedc:b00) 23, but this is the fault when run run it config tool,: Network error, software caused connection abort. If not run config tool PuTTy immediately quit.

How can I fix it in such case?
