[RC5] PProxy & Firewall Problem

I have about 7 machines running the RC5DES client which have been
running fine through a MSProxy 2 proxy/firewall for a couple of months
now. Everything being perfectly stable, I decided to try and make life
difficult for myself by setting up a pproxy now that the pproxy can run
through a http proxy.

I can't seem to get the pproxy to talk to the outside world though. I
have setup the pproxy correctly as far as I can tell.

Here is an example of a typical log from my pproxy...

[03/23/98 08:48:24 GMT] Server 128 added to slot 1 ip 1.20.1.100 port 80
[03/23/98 08:48:24 GMT] rc564 r=0/250, d=1371/10, des r=0/250, d=9/10
[03/23/98 08:48:24 GMT] 0d 2:08:28, 1.1 rc5 Mkeys/sec 0.0 des Mkeys/sec
[03/23/98 08:48:24 GMT] Status: Slot 0 LISTENING
[03/23/98 08:48:24 GMT] Status: Slot 1 idle   0 ip 1.20.1.100 SERVER
[03/23/98 08:48:24 GMT] Status: Slot 2 idle   1 ip 1.20.1.100 SERVER
[03/23/98 08:48:24 GMT] The proxy says: DES-II.IS.OVER!...Crack.RC5-64!
[03/23/98 08:48:24 GMT] Closing HTTP connection for server 1.20.1.100
[03/23/98 08:48:25 GMT] Server 148 added to slot 2 ip 1.20.1.100 port 80

It seems to be talking to the keyserver (alde.com, I have also tried
just the IP address) but doesn't get any blocks, or send any blocks...

I have tried both port 80 and 2064 for the pproxy to talk to the
keyserver on.

I am running WinNT 4 workstation. Latest pproxy for win32 running as an
NT service and the NT service client on the same machine.

Pproxy .ini file:

Copy of .ini from GUI client that can talk to alde.com no probs thru my

Typical output from a client trying to go thru my pproxy...

Wow! You've read all the way to the bottom of this really long message!!
:-) Now that you're hear, do you have any suggestions on how to fix
this? 

Thanks,

Todd.
