I have access to the office from outside (VPN, e-mail, etc.). I have at home Internet from ISP(A) and at office from ISP(B). Everything were working fine till I received an e-mail from my ISP(A) that they needed change my public IP. From that moment I lost the connection with the office.
I checked everything from the office side and I don't see problem, for more, I can connect from other places without problem, even with the phone data connection is possible connect, so, I don't believe the issue come from the firewall at office.
I contacted to ISP(A) and they told me there is everything ok, they asked me for contact the ISP(B). I called to ISP(B) and they asked for the 'phone number' of my connection with ISP(A), but what I have from ISP(A) is a wireless connection (WiFi) with an Ubiquiti antenna, but ISP(B) insist that 'every Internet connection have a associated phone number'. Now I wrote to ISP(A) asking for that number, but I really don't understand how a phone number can be associated to a WiFi connection?? I didn't have answer yet.
For try to find the problem I tried:
- Telnet to different ports, and never connect. Again, from other ISPs Telnet can connect
- Traceroute and the packets died in an IP which belong to ISP(B), but I tried from others connection and always the packets are lost in the same IP, I believe there is something blocking the ICMP.
What more can I check and how can I debug where is the problem??
UPDATE:
Pfsense won't log all rules by default, so before I didn't see nothing in the logs, and by the rules are defined I believed everything look good. Now I started to log everything and I see the firewall is blocking the IP as a 'bogon network'. Concretely I get: b

Finally updating the bogon networks list on Pfsense was the solution.
