SG-1100 IPv6 WAN

Timmy

Hi all,

This is a bit of a long shot. I am trying to get IPv6 working on my SG-1100. My ISP has a beta for IPv6 running, and there are details on how to set it up on their end, and on pfSense. I have friends who have it all working (same ISP), but they are running pfSense on Intel-based PCs, where as I am running it on an SG-1100.

Instruction on setting it up:

WAN Settings
Menu: Interfaces – WAN
IP Configuration Type: DHCP6

DHCPv6 Prefix Delegation size: 56
The following options only should be checked:

Send IPv6 prefix hint
Do not wait for a RA

There are other settings across the LAN interfaces and route configuration.

I think the issue I am having is something to do with how the SG-1100 manages the external ports and the internal virtual switch - only real difference I can see between my router and friends who run pfSense on Intel boxes. I have had a couple of gotchas with the switch config before (got it all working, just missed some steps).

DHCP6 log

Sep 5 18:57:36	dhcp6c	95857	Sending Solicit

Sep 5 18:57:36	dhcp6c	95857	reset a timer on mvneta0.4090, state=SOLICIT, timeo=206, retrans=125424

Interface config - (note: I have other VLANs configured for IoT and Guest access, which are all working fine):

VLAN group	VLAN tag	Members	    Description
0	        1	        0	    Default System VLAN	
1	        4090	        0t,3	    WAN	
2	        4091	        0t,2	    LAN	
3	        4092	        0t,1	    OPT

I only get a link local address on the WAN interface (A,B,C, and D replacing actual) %mvneta0.4090 is how it is shown in the interface and on ssh:

IPv6 Link Local
fe80::AAAA:BBBB:CCCC:DDDD%mvneta0.4090
From ifconfig:

mvneta0.4090: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500

	options=3<RXCSUM,TXCSUM>

	media: Ethernet 1000baseT <full-duplex>

	nd6 options=23<PERFORMNUD,ACCEPT_RTADV,AUTO_LINKLOCAL>

Thanks for any advice.

They may be sending a prefix only in which case the WAN would not get an IPv6 address directly and would using link-local for routing the prefix. My ISP does that.
If you have LAN or OPT set to track WAN with prefix ID set they should get a v6 IP.

Enable Debug in the dhcpv6 settings on WAN and you will get a lot more logged info when it connects.
