Don't forget about the option of HTTP tunneling. Basically what that does is to encapsulate all dnet data inside HTTP packets so to the firewall it looks like you're just browsing the net.
[networking]
nofallback=true
autofindkeyserver=no
keyserver=proxy80.teamanandtech.com:80
firewall-type=http
firewall-host=<your_proxy_server>:<your_proxy_port>
If your proxy server requires authentication, you'll have to go through the config menu to enter them because this info will be encrypted and not stored in the ini file as clear text. Good luck to you A-starand death to the firewall!
Regarding the host name vs. host address thingy, I think I found a setting in the proxyper.ini that may help. RaySun2Be, would you mind trying my pproxy again using host name? If it works, I'll reveal the secret ingredient! If not, oh well, my name is clueless! 😉
