Is anyone else experiencing this issue? I have no reliable internal DNS resolution while this issue continues.

This issue is still ongoing after restarting unbound and dhcpv6

Hi,

I have static IPv6 addresses assigned for some devices on the network.

Since I have a dynamic WAN IPv6 prefix, these addresses are set as, e.g. ::1. DHCPv6 automatically assigns them the IPv6 address of <WANPREFIX>::1

However, unbound DNS is only picking up the static mapping of ::1 and is returning that as the AAAA record:

Code Select Expand

nslookup computer.mydomain.tld
Server:  OPNsense.mydomain.tld
Address:  xxxx:xxxx:xxxx:xxxx:2e0:67ff:fe1f:23f9

Name:    computer.mydomain.tld
Addresses:  ::1
          192.168.1.105

I think this is a bug in unbound. Is anyone else having the same issue?

Ok it seems you were correct with the switch. I completely rearranged everything and made use of one of the spare physical ports on the firewall to create a new physical lan just for the TV and it's working properly again.

Thanks for your help.

Issue persists after a reboot

IGMP snooping is enabled on the switch for VLAN 1 (I'm not currently using VLANs)
Validate IGMPv3 IP header - Enabled
Block Unknown Multicast Address - Disabled

I'm using no virtualisation. It's running on a protectli 4 port firewall.

Hi,

I'm seeing an issue where my igmp streams from the IPTV subscription are dropping after around 6-8 minutes.

I have attached the verbose igmpproxy logs and noted where the stream dropped. I can't see anything in there that would suggest that the stream has been dropped/terminated.

Multicast comes from the 109.159.247.0/24 range. The igmpproxy settings are as follows:

Code Select Expand

root@OPNsense:~ # cat /usr/local/etc/igmpproxy.conf

##------------------------------------------------------
## Enable Quickleave mode (Sends Leave instantly)
##------------------------------------------------------
quickleave
phyint igb1 downstream ratelimit 0 threshold 1
altnet 192.168.1.0/24

phyint igb0 upstream ratelimit 0 threshold 1
altnet 109.159.247.0/24
altnet 224.0.0.0/4

phyint igb1_vlan60 disabled
phyint pppoe0 disabled

Currently, I'm restarting igmpproxy manually every time the stream drops...! I can do some tests if there's anything you'd like me to test.

Regards
Ben
