      Hi,

      As newbie on the pfsense platfrom and i encounter an issue with 2.1-BETA0 (i386) built on Fri Oct 5 11:51:37 EDT 2012 FreeBSD 8.3-RELEASE-p4.

      My DSL provider XS4All in The Netherlands provides native ipv6, i have an fritzbox 7170 as modem between the ISP and my Alix 2d13 with pfsense. (ipv4 works like a charm)

      I receive the ipv6 dns servers in my dns server list and I have set dhcpv6 in the ipv6 settings with a prefix mask of /64.

      However I do not get an ipv6 address from the provider.

      In the logs I receive the following errors:

      Oct 6 21:18:53 syslogd: exiting on signal 15

      Especially the DHCP6 option opt_20 seems strange and in my opinion blocks receiving the ipv6 address.

      Can anyone help me with this?

      I run my pfsense in multi wan setup with UPC (Dutch cable provider) and XS4All (DSL provider) on one box (hence 2 interface names UPC and XS4All)

      Thanks in advance,

      Regards,

      Epco
