Help setting up IPv6 on PPPoE

Installing and Using OpenWrt Network and Wireless Configuration
1

Hey Guys,

I have a simple network that was supposed to provide ipv6. But whatever I do I can't seem to get my devices to get ipv6. Previously when I was using stock Xiaomi firmware enabling native ipv6 requests it requested the ipv6 properly. But now in OpenWrt, it doesn't work. I also try reverting back to stock firmware and it still doesn't work there now also. Is this isp sided issue or something's wrong with my config?

Provider Router/Modem --> OpenWRT --> My Machine

I got some info on my setup using these commands from a different forum post.

uci export network; uci export dhcp; uci export firewall; \
head -n -0 /etc/firewall.user; \
iptables-save -c; ip6tables-save -c; \
ip -4 addr ; ip -4 ro ls tab all ; ip -4 ru; \
ip -6 addr ; ip -6 ro ls tab all ; ip -6 ru; \
ifstatus wan6; ifstatus lan

Output:

~7 minutes it starts on PPPoE and WAN6 (not specific to this device)

This doesn't show ipv6 related issue. But I also tried something like this.

I think the issue is isp sided and for some reason, I am not being assigned the ipv6. Contacting them and getting past their normal customer care is kind of annoying. They told me to try plugging into the computer directly and check. As the connection isn't long enough to reach my desktop, I'll need to wait until tomorrow to bring my office laptop back and check.
