[vorr]

Hi, i wanted a better quality router and i installed pfsense 2.1-RC1 (amd64) NanoBSD 4g built on Wed Aug 28 and every works ok except when i tried to see what packages are available for this build and i came across the follwing error"
"Unable to communicate with www.pfsense.com. Please verify DNS and interface configuration, and that pfSense has functional Internet connectivity."

i did the following troubleshooting on the shell prompt

tested if i can ping

ping www.pfsense.com

i tried to get something

fetch -o /tmp/test http://www.pfsense.com

(after 90seconds of waiting/timeout)

/tmp/test                                     100% of   13 kB   41 kBps

but

fetch -o /tmp/test http://192.207.126.26/

(1 second delay)

/tmp/test                                     100% of   13 kB   40 kBps

some more fetches

fetch -o /tmp/test http://www.google.com/

(30 seconds delay)

fetch -o /tmp/test http://www.otenet.gr (my provider)

(instant)

my connection is pppoe and ive set mtu 1492 and mss 1452

i still cant figure out how to solve this problem, any hints?

EDIT:

tried diagnostics-> nslookup , it takes 30 seconds to bring back result

running it from prompt is instant

You seem to be mixing .org and .com in your tests. I assume you tried both?

I didnt mix anything, pfense.org and pfsense.org are the same, if i try and ping pfsense.com it resolves to pfsense.org

Another guy with messed up IPv6 connectivity?

env ip6addrctl_enable="yes" ip6addrctl_policy="prefer_ipv4" /etc/rc.d/ip6addrctl start

[vorr]

it seems so, running the command fixed the problem. The thing is, i didnt mess up with any setting so could it be that the default settings dont work out of the box? my isp has dual stack but i dont see any ipv6 address anywhere. i guess it will be fixed it a future update. thank you very much for your reply

[doktornotor]

Well, not really possible to help without knowing how does the ISP "ship" the IPv6 connectivity to customers. Usually documented somewhere on their web.

i did some search on how my isp servers ipv6 and i found some info for a router zte w300 if it suggests
For WAN
DHCP  IPv6 Mode: SLAAC
DHCP PD: Enable
MLD Proxy: Disable

For LAN
Radvd Enable: Enable
Radvd mode: Auto
DHCP6 server: enable
DHCP6 mode: auto
