PF, two Internet connections, and servers
I have two network connections in my dorm room, and would like to set up my OpenBSD router to use them both (the box has three NICs). I would like most of my traffic to be routed through one of the connections, and use the other for my Webserver. Here is a copy of my pf.conf I have been playing around with for this:
Code:
# macros |
OK, I got it to work. Here is my new pf.conf:
[CODE] # macros int_if = "rl0" ext_if1 = "dc0" ext_if2 = "rl1" tcp_services = "{ 113 }" icmp_types = "echoreq" priv_nets = "{ 127.0.0.0/8, 192.168.0.0/16, 172.16.0.0/12, 10.0.0.0/8 }" webserver = "192.168.2.1" desktop = "192.168.2.3" # options set block-policy drop set loginterface $ext_if1 # scrub scrub in all # nat/rdr nat on $ext_if1 from $int_if:network to any -> ($ext_if1) nat on $ext_if2 from $int_if:network to any -> ($ext_if2) rdr on $int_if proto tcp from any to any port 21 -> 127.0.0.1 \ port 8021 rdr on $ext_if2 proto tcp from any to ($ext_if2) port 80 -> $webserver rdr pass on $ext_if1 proto { tcp, udp } from any to ($ext_if1) port 7500 -> $desktop rdr on $ext_if1 proto tcp from any to ($ext_if1) port 6881 -> $desktop rdr on $ext_if1 proto tcp from any to ($ext_if1) port 5190 -> $desktop # filter rules block all pass quick on lo0 all block drop in on $ext_if1 from $priv_nets to any block drop out on $ext_if1 from any to $priv_nets block drop in on $ext_if2 from $priv_nets to any block drop out on $ext_if2 from any to $priv_nets pass in on $ext_if1 inet proto tcp from any to ($ext_if1) \ port $tcp_services flags S/SA keep state ############# #Pass rules for forwarded ports. pass in quick on $ext_if2 proto tcp from any to any port 80 \ flags S/SA modulate state pass in on $ext_if1 proto tcp from any to $int_if port 7500 \ flags S/SA synproxy state pass in on $ext_if1 proto udp from any to $int_if port 7500 pass in on $ext_if1 proto tcp from any to ($ext_if1) port 5190 \ flags S/SA synproxy state pass in on $ext_if1 proto tcp from any to ($ext_if1) port 6881 \ flags S/SA synproxy state pass in on $ext_if1 inet proto tcp from port 20 to ($ext_if1) \ user proxy flags S/SA keep state ############ #Let's let OpenVPN traffic through... pass quick on tun0 ############ pass in inet proto icmp all icmp-type $icmp_types keep state pass in on $int_if from $int_if:network to any keep state pass out on $int_if from any to $int_if:network keep state pass out on $ext_if1 proto { tcp, udp, icmp } from any to any flags S/SA modulate state pass out on $ext_if2 proto { tcp, udp, icmp } from any to any flags S/SA modulate state [CODE] |
