IPv6 No Gateway after 2.5 upgrade
-
I have the same problem after update to 2.5.0
IPv6 is working but there is no gateway.
Netgate 6100 MAX
-
pfSense has the IPv6 gateway but is not showing it under Interfaces tab and widget.
After I reboot the cable modem I again getting IP addresses but then no IPv6 connection. Pinging also isn't possible anymore. Tried everything only rebooting pfSense works.
BUT: my second WAN (PPPoE DSL) is working without any issues. It's only the cable connection. Both connections use the same IPv6 config to get the /56 prefix (that seems working) and the PPPoe also is getting IPv6 Gateway. The cable does not.

@mrsunfire Please attach the
/var/log/dhcpd.logfile for checking -

This worked for me. Now passes on all IPv6 test sites I tried.

As suggested, manually adding the Monitor address seems to solve part of the issue, though with Gateway hardcoded as "dynamic", it seems to affect the ability to use it in firewall rules -- CoDel Limiters, for example below.
21:00:51 There were error(s) loading the rules: /tmp/rules.debug:223: no routing address with matching address family found. - The line in question reads [223]: pass out quick on { igb1 } $GWWAN_DHCP6 inet6 from any to any tracker 1610764779 keep state dnqueue( 2,1) label "USER_RULE: CoDel Limiters" -
@amessinamessinet-com I am having the same issue.

@amessinamessinet-com This is the problem I'm having as well. I set the monitor address to the link-local address but now my CoDel Limiter for IPv6 is giving that error.

Yep... See this bug: https://redmine.pfsense.org/issues/11454
As you mentioned, only part of the issue has a workaround (the monitoring, which affects IPv6 connectivity as a whole). The gateway selection part will likely require an update to pfSense once fixed.

Still no ETA for a fix? IPv6 is unusable after WAN fails one time.
-
@anzenketh said in IPv6 No Gateway after 2.5 upgrade:
I can ping ipv6.google.com with IP protocol IPV6 from Diagnostics -> Ping
That's where I am on an SG-2100 with 21.02, I can ping that from my PC behind it.
Status/Interfaces has a default route for IPv6.The router has a default route for IPv6 in Diagnostics/Routes, just no gateway for IPv6 shown in Status/Interfaces.It sounds like some people have IPv6 connectivity and some don't? Essentially for me it's just a cosmetic issue with the GUI. After upgrade I (re)installed pfBlockerNG-devel and Snort but didn't reboot again.

I noticed that both /tmp/em0_routerv6 and /tmp/em0_defaultgwv6 were empty while the ipv4 versions had the valid router addresses in them. Both of these are set in the script /var/etc/rtsold_em0_script.sh which is built by the script /etc/inc/interfaces.inc. It looks like the parameter is not being passed to the script. I modified the routine in interfaces.inc that builds the resold_em0_script (search for "rtsoldscript") to set a hard coded value for both these files and my IPv6 gateway started working! Routing, firewall rules, Policy Based Routing, etc, all work!
My mods:
#echo $2 > /tmp/em0_routerv6
echo "fe80::X:X:X:X" > /tmp/em0_routerv6
#echo $2 > /tmp/em0_defaultgwv6
echo "fe80::X:X:X:X" > /tmp/em0_defaultgwv6After I made the mods, I "saved" the WAN interface again without making any changes. Hope this helps someone until a real fix is pushed out.

@g-shaffer Worked for me, thank you!
-
@mrsunfire - thank you. It is working for me here.
-
I'm also seeing this issue.
@g-shaffer What are you setting as the "hard coded value"? The Link Local IPv6 address of the WAN?
-
@randyshoopman I got it by looking for the "receive advertise from ..." in the dhcpd.log, but you should be able to use the default IPv6 route address (minus the %interface) listed in the default route table (Diagnostics -> Routes).
-
@g-shaffer I don't seem to have any log entries in my dhcp.log with that exact text. In any case the default route has an fe80 link local address. I will try that -- thanks

@g-shaffer Hi, I did this change with the result that I got a static IPv6 address to monitor.
Btw. This can slo be done here -> System - Routing - Gateways - Edit WAN_DHCP6 -> Monitor IPBut now come the strange part: After I realised that I can do this also in the configuration I revert the change to
$rtsoldscript .= "# This shell script launches dhcp6c and configured gateways for this interface.\n"; $rtsoldscript .= "echo $2 > {$g['tmp_path']}/{$wanif}_routerV6\n"; $rtsoldscript .= "echo $2 > {$g['tmp_path']}/{$wanif}_defaultgwv6\n"; $rtsoldscript .= "/usr/bin/logger -t rtsold \"Received RA specifying route \$2 for interface {$interface}({$wanif})\"\n";It works. I can not explin why but it works :)
Cheers
Marco
