I'd appreciate the compile. I understand it's only sample code, but it's the only thing out there. If it doesn't work then I haven't lost anything. I assume I take the .dll, drop it into the ...Microsoft Isa Server directory, regsvr32 it, and it should appear in the ISA MMC? Thanks again! ----orig Subject: Re: re Re: SOCKS5 Compiled? From: "Jim Harrison" <jim@xxxxxxxxxxxx> I can compile it for you, but there's no guarantee of stability or functionality. It's only sample code; instructional and "basically functional". YMMV... ----- Original Message ----- From: "SteveC" <SteveC@xxxxxxxxxxx> The SOCKS4 filter is not doing UDP. I have Macintosh clients that need to use UDP just like the Win folks do with the Firewall Client. After reading through some references on the web, I was led to believe that the SOCKS5 filter would let me supply UDP to non-Win clients.
