Enabling IPv6 with a static IPv4 (Dasan H680GM-A)

[superczar]

whoa, @Strykar so if i am reading this right, port 80/443 are not blocked on non static at the back end but at the router level ?

I am on a different router model and had static ipv4 till recently which broke after the ipv6 rollout.
Since i need port 443 (home Assistant), i am doing a VPN punch hole via an AWS lightsail server + wireguard.

It took a fair bit of finagling to get dual stack working on my opnsense router so I do not want to mess it up by re raising a static IP request .. they had enough trouble setting it up on ipv4 .

So if i could get ssh access to my router, i should, at least in theory be able to remove the offending line in iptables and that should be it?

Yeah the ports are not blocked. You can forward 80/443

Thanks @albonycal
My CPE model is AOT-4221SR .
Let me see if i can figure out getting shell access to it

^ AOT-4221SR is ok ok ... try bridge mode with ur personal router ....

 

[superczar]

its in bridge mode only since a long time... Sophos XG earlier for the last few years and now opnsense

With ipv4 and dynamic IP, 80 and 443 were blocked (rest open)
with ipv4 and static , all ports were open

Now i am on ipv6 and dynamic ipv4 - and 80/443 are blocked

any success using the USB port? I've successfully unlocked this router, but I can't seem to locate the USB option. All settings are accessible now, and post-unlock, it displays Software Version 2.06-0011

USB port works fine, but not via the web interface, no.
However, dmesg shows a pen drive being attached and mounted to /mnt/usb1_1/ so you could access it if you were really desperate over something like SSHFS or CIFS, I have not attempted to setup either or tried attaching a USB printer etc. to see if other types of devices besides storage are supported.

Has anyone been successful in retrieving the default or superuser credentials after Airtel upgraded the firmware?
This and H660GM-A both have the same credentials.
