There is simple ipchains+masquerading firewall (ie packet filter). UDP
for masquerading is set to 120 (+_ something) and CIPE pings every 30 seconds
(just to keep the link up). So I don't think there is problem with timeouts on
firewall. I will reconsider it once more.

I think that transferring whole screen causes "burst" of data and the
on the way (W2K <-eth-> Linux <-CIPE-> Linux <-eth-> W98) is't able to cope
that. I suspect the W2k but I'm not sure. Strange.
