Hi, I am having some troubles figuring out how to get a remote PCAnywhere station log onto a local pcanywhere station. Here's my config: Firewall : (eth0 : external IP) - a.b.c.d (eth1 : internal IP - 192.168.5.17) Int IP (one with PCAnywhere) : 192.168.5.31 Here's my attempt at a netfilter script for this: iptables -A INPUT -i eth0 -d 192.168.5.31 -p tcp --dport "5631:5632" -j ACCEPT iptables -A INPUT -i eth0 -d 192.168.5.31 -p udp --dport "5631:5632" -j ACCEPT iptables -t nat -A PREROUTING -i eth0 -d a.b.c.d -p tcp --dport "5631:5632" -j DNAT --to 192.168.5.31 iptables -t nat -A PREROUTING -i eth0 -d a.b.c.d -p udp --dport "5631:5632" -j DNAT --to 192.168.5.31 I actually got this off the net and am still trying to disect it. Am I supposed to have Output, or just forward chains since in essence I'm just forwarding the PCA packets to a different station? I'm still barely understanding Netfilters. For the other services (smtp, www, etc...) they are working. I don't understand why I'm having so much trouble with PCAnywhere. Thanks Edmund
