BSD ports behind a unfriendly firewall

["hamish" <hamish@moorefamily.cx>]

My OBSD box at works sits behind a firewall that I have no control over. 
They provide us with gateways for telnet and ftp.

To grab a copy of the latest ISO I would have to do the following

ftp gateway.myisp.com.au

I would be prompted with a 

login: 

where I would type 

anonymous@ftp.aarnet.edu.au

after this I can use all the normal ftp commands to get around the site and
download anything I want.

Because ftp,web and telnet are the only tcp ports allowed outgoing..  Is
their anyway ..the I can get BSD's software ports to work ?

My apologies if this has been sent to the wrong list.

kind regards
Hamish
