Your local address is in unroutable address space. Your NAT renumbers TCP source ports sequentially. The following graph shows connection attempts on the X-axis and their corresponding source ports on the Y-axis. port sequence plot DNS-based host information: OK You are not a Tor exit node for HTTP traffic. You are listed on the Spamhaus Policy Based Blacklist, meaning that your provider has designated your address block as one that should not be sending any email. The SORBS DUHL believes you are using a dynamically assigned IP address. Reachability Tests General connectivity: Note Basic UDP access is available. Direct UDP access to remote DNS servers (port 53) is blocked. The network you are using appears to enforce the use of a local DNS resolver. Direct UDP access to remote MSSQL servers (port 1434) is blocked. This is most likely due to a filtering rule against the Slammer worm. Direct TCP access to remote FTP servers (port 21) is allowed. Direct TCP access to remote SSH servers (port 22) is allowed. Direct TCP access to remote SMTP servers (port 25) is allowed. Direct TCP access to remote DNS servers (port 53) is allowed. Direct TCP access to remote HTTP servers (port 80) is allowed. Direct TCP access to remote POP servers (port 110) is allowed. Direct TCP access to remote RPC servers (port 135) is blocked. This is probably for security reasons, as this protocol is generally not designed for use outside the local network. Direct TCP access to remote NetBIOS servers (port 139) is blocked. This is probably for security reasons, as this protocol is generally not designed for use outside the local network. Direct TCP access to remote IMAP servers (port 143) is allowed. Direct TCP access to remote SNMP servers (port 161) is allowed. Direct TCP access to remote HTTPS servers (port 443) is allowed. Direct TCP access to remote SMB servers (port 445) is blocked. This is probably for security reasons, as this protocol is generally not designed for use outside the local network. Direct TCP access to remote SMTP/SSL servers (port 465) is allowed. Direct TCP access to remote secure IMAP servers (port 585) is allowed. Direct TCP access to remote authenticated SMTP servers (port 587) is allowed.
