IPv6 on multiple LAN's

IPv6 with multiple LAN's

I think I'm missing a small piece of the puzzle.
I'm able to get IPv6 to work on my primary LAN, but not on an additional TEST LAN.
With a little research, I found that Comcast will work with:

WAN interface (em0)
General Config
IPv6 Config Type DHCP6
DHCP6 Client Config
DHCPv6 Prefix Delegation size 59

l)

The pfSense Dashbord shows
WAN, LAN, TEST interfaces all UP with both ipv4 and ipv6 addresses

LAN interface (em1)
Able to ping -6 to various sites and reach IPv6 test sites
General Config
IPv6 Config Type Track Interface
Track Ipv6 Interface
IPv6 Interface WAN
IPv6 Prefix ID 0

Services / DHCPv6 Server & RA
Enable Checked
Range ::1000 ::2000
Prefix size 48

Able to ping -6 to various sites and reach IPv6 test sites

TEST interface (em3)
General Config
IPv6 Config Type Track Interface
Track Ipv6 Interface
IPv6 Interface WAN
IPv6 Prefix ID 1

Services / DHCPv6 Server & RA
Enable Checked
Range ::1000 ::2000
Prefix size 48

I get IPv6 Address and Default Gateway on a PC on the TEST LAN
ping -6 google.com results in
Pinging google.com [appropriate IPv6 address] with 32 bytes
Request timed out.

The pfSense / freeBSD console shows
WAN (wan) -> em0 -> v4/DHCP4: 24.3.26.10/23
v6/DHCP6: 2001:558:6035:e:a822:46cb:d41e:7c2d/128

LAN (lan) -> em1 -> v4: 192.168.2.1/24

GUEST (opt1) -> em2 -> v4: 192.168.30.1/24

v6/t6: 2603:301f:f00:0:e61f:13ff:fefa:66d2/61

from ifconfig

inet6 fe80::1:1%em1 prefixlen 64 scopeid 0x4

I would appreciate any suggestions.

prefixlen 61

Why are you getting that? The LANs should be /64. I don't see any configuration info.

[tpalmer0127]

Not sure why it's /61. I don't see anywhere that I set that.
What "configuration info" are you asking about ?

Your WAN and LAN configuration settings. All I see are firewall rules.

[tpalmer0127]

The configuration that I changed are in the text of the message. I can post images too.

Configurations for WAN, LAN, TEST

Prefix size 48

Is that what your ISP is providing? The image for the WAN interface is a bit blurry, but it looks like you've selected 59. I have 56 for my ISP. Both 56 and 48 are common, though you can chose anything up to what your ISP provides. Also, you may want to select Send IPv6 prefix hint.

[tpalmer0127]

Prefix size for WAN is set at 59. That was recommended in a post perhaps on this forum. I can try other size

[tpalmer0127]

Changed to 56 and IPv6 works on the TEST lan.
Thanks for the help

@tpalmer0127

What does your ISP provide? Earlier you said /48.
