I can't access my server remotely at port 80. First of all, I did not set it up. Someone else did. I am not a sysadmin. But communication between both parts (me and sysadmin) takes time and deadlines await, so I decided to take matters into my own hands. After all I have root access.
It seems to me there is a Firewall issue, but how can I resolve it?
This is what I get from my side:
chris@mint-desktop ~ $ nmap -Pn remote_server -p 80 Starting Nmap 6.00 ( http://nmap.org ) at 2014-07-01 16:28 EEST Nmap scan report for remote_server (remote_addr) Host is up. rDNS record for remote_addr: rDNS_record_for_remote_addr_seems_valid PORT STATE SERVICE 80/tcp filtered http Nmap done: 1 IP address (1 host up) scanned in 2.13 seconds
This is what I get server-side:

However, when I hit the remote name on my web browser, I get no response. Logs say that there was a hit yesterday internally, but no external access. So, I guess the sysadmin tested it and realized it was up. But I can't access it.
