I wondered if anyone could assist me in writing a simple packet filter firewall on my OpenBSD v4.5.
All I intend doing is to have two firewalling machine on a separate network :
ext_if = xl0 (dhcp)
ext_if = rl0 = 192.168.0.120 (static IP)
int_if=rl1 = 192.168.2.20
My problem is I could not have a connection from the second machine due to the packet filter rules. Please I wondered if anyone could send me a brief explanation on this. I am not running a webserver or services to the outside world.
