Forum doesn't work from ipv4

[f1rs]

Hi.
First of all sorry for my English.
I have a problem with connection to this forum through ipv4 addresses.
But with ipv6 address all works fine.

"Host" result:
forum.pfsense.org has address 69.64.6.7
forum.pfsense.org has IPv6 address 2605:8000:d:1::151

Do you see any problems with configuring your web-server or it's a new feature and this forum will be works only through ipv6?
Thanks.

Hi!
First of all i want to say that the resourse is unreachable no from all ipv4 addreses and it's blocking an icmp requests:
traceroute 69.64.6.7 -A
traceroute to 69.64.6.7 (69.64.6.7), 30 hops max, 60 byte packets

It seems, that resourse blocks access from network 92.60.186.0/28:

#telnet 69.64.6.7
Trying 69.64.6.7, 80 …
% Connection timed out; remote host not responding

I can't connect to the server on port 80 through telnet with sourse addreses 92.60.186.0/28

But connection establishing succesfuly when i try to connect using another ip-adddress space.

Please, explain my why do you block connection from 92.60.186.0/28 address spase?

Thank you!

These ip-addresses belongs to Wnet-Ukraine ISP

[Metu69salemi]

are you using pfblocker or something else, which is blocking forum.pfsense.org?

[serg]

No, i don't use any sotf that can block my connection! no firewall, no iptables, etc… As i wrote in my previous post, i can't establish telnet connection to port 80 from ip-address space 92.60.186.0/28, but connection establishing sucsesfully from other ip-address spaces that also belong to Wnet ISP such as 217.20.191.0

i don't have any troubles with my equipment, i know exactly that site blocks my connection from some ip-addreses. I have only one question, why?

[jimp]

A bunch of subnets were blocked the other day because there was a ton of forum spam originating from within them.

The closest matches I see are:

92.60.176.0/20

Which goes from 92.60.176.0-92.60.191.255

So you're included in that list, which is marked as being part of RBN, a large source of spam and other harmful traffic (See http://en.wikipedia.org/wiki/Russian_Business_Network )

We pull that list from http://doc.emergingthreats.net/pub/Main/RussianBusinessNetwork/RussianBusinessNetworkIPs.txt
