I have 3 boxes on my lan. 1 RH7.2 with kernel 2.4.9 and iptables-1.2.5 a dialup ppp0 with dynamic IP and squid. Using a most basic form of iptables ie. All policy are ACCEPT iptables -t nat -A PREROUTING -i ppp0 -j MASQUERADE The problem is, for a short time after I dialup everything works to plan. Then and I'm not sure if it's when accessing the net from 2 boxes at the same time but data stops flowing. Web, POP, SMTP can't get through but pings work fine. Any ideas! Thanks. Jai.
