Hello,
Could anyone help me please?
I'm trying to connect from 192.168.0.3 to 192.168.0.1:8080 and send that to 192.168.1.2:80 as if it were coming from 192.168.1.1.
Pretty silly but I don't know how. I've tried the following:
Code:
int_if1 = 192.168.0.1 #re0
int_if2 = 192.168.1.1 #re1
client = 192.168.0.3
server = 192.168.1.2
pass in on $int_if1 inet proto tcp from $client to $int_if1 port 8080 rdr-to $server port 80
pass out on $int_if1 inet proto tcp to $server port 80 received-on $int_if1 nat-to $int_if2
Code:
test# tcpdump -n -i re0 port 8080
tcpdump: listening on re0, link-type EN10MB
