I set up port forwarding to allow Transmission (BitTorrent) to receive incoming connections from my VPN. I can access the port if I use my public IPv4 address, but not my public IPv6 address. The release notes do not mention that IPv6 support was added to the firewall, so presumably this is something we can expect to see in a future firmware upgrade?
I’m new to IPv6, so I’m still not exactly sure what I need to do, if I want to open up ports. I saw this on the OpenWRT Wiki:
config rule option src 'wan' option proto 'tcp' option dest 'lan' option dest_ip '2001:db8:42::1337' option dest_port '80' option family 'ipv6' option target 'ACCEPT'
I haven’t tried it, but it looks like it might work. Trouble is, my IPv6 address is not static (as far as I’m aware), so this would not persist across VPN sessions.
This might not be a problem. Perhaps BitTorrent is robust enough to fall back to IPv4 if there are problems with IPv6?
