My experience is that many firewalls, well, many NAT routers which are often used as firewalls, ignore keepalive. It seems to me a poor design decision, but I have seen many do that. As for TCP, as far as I know it, it is not the honoring of keepalive, but that someone has to send them. -- glen ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
