IPsec spadne pri prenosu velkeho souboru

[Večeřa Antonín]

Kratce:

Mam nastavene IPsec mezi FreeBSD a WinXP.
V okamziku kdy zacnu prenaset velke mnozstvi
dat, tak mi FreeBSD po chvili prestane komunikovat.
Setkal se nekdo s necim takovym?
Kde by mohl byt problem?
Budu vdecny za dazdy namet...

-----------------------------------------------------
Podrobneji:
Na WinXP otevru SSH a zacnu prenaset testovaci soubor
o velikosti asi 360MB. VZDY takrka presne ve 42% mi
spadne komunikace.
Musim na WinXP shodit IPsec (pote se stale nepripojim
na FreeBSD) a resetnout FreeBSD. Po nabehnuti se uz
muzu nalogovat.

Nejaky klic vyexpiruje?
Nebo pretece nejaky buffer?
