PSA Block bogon networks breaks WAN DHCP6



  • After struggling with this thinking I was having the DHCP6 won't renew issue others are seeing, I discovered that the firewall was actually blocking the DHCPv6 responses from my ISP (Comcast). Checked the firewall logs and it was the block bogon networks rule. Disabled that option on the wan interface and immediately got my DHCPv6 address and and my internal track interface started working.

    Just wanted to save anyone else the trouble of discovering this.

    THanks for letting me in on that tip. I will have to try this tonight when I get home. I was also having other issues with my Comcast device and that is now fixed. So hopefully I can get this working as I would love to start playing with some firewall rules.
