well i have seen a similar procedure when i was making my proxy server.
Mirc alwais trys to make a direct connection, so when one of the clients is inside of a lan protected by a proxy firewall, if it is sending a file (ole), and the other client (tontito) can't connect, it requests that the original client(ole) makes the connection to send the file(in original protocol, the sender only waits to recive the connection)
example:
ole -> DCC SEND phpBB-2.0.6.zip 2130706433 0 672919 127
tontito -> DCC SEND phpBB-2.0.6.zip 2130706433 2211 672919 127
has you noticed there is a extra field (since ole is configed to make dcc pass to proxy), that originaly was 0 then it was changed to 2211 (port were tontito is now listining for a connection to recive the file)
i know this sounds a bit confusing, it also confused me (now imagine try to resume a connection) :tongue:
