setting up a proxy server in OpenBSD 4.3

[jrake]

Good day guys...

First of all I'm not expert either in Linux or Unix but I'm curious how things done in this platform so I setup a proxy server in my newly installed OpenBSD 4.3

here is some info in my box:

hostname.rl0:
IP: 124.6.155.51
broadcast: 124.6.155.63
gateway: 124.6.155.49

hostname.rl0:
IP: 172.16.1.12
broadcast: 172.16.1.255

edited 2 lines at squid.conf
acl our_networks src 172.16.1.0/24
http_access allow our_networks

NOTE: no pf enabled

edited 2 lines in sysctl.conf
net.inet.ip.forwardin=1
vm.swapencrypt.enable=1


If I try to change one of the client pc gateways ip address as 172.16.1.12 and the DNS into "124.6.155.51", I get an error message "The Connection has timed out" ..
In a client PC if I try to ping 124.6.155.51 I received an answer but when I ping 172.16.1.12 I get "REQUEST TIMED OUT".

Any idea or suggestions that can help me is very much highly appreciated..

I strongly recommend reading more on the subject and carefully following a known-good example configuration.

I recall that you need to enable 'pf' and add RDR rules if you want to use Squid as a 'transparent' proxy.

You can use Squid as an 'explicit' proxy (by putting proxy settings in the browser, or using WPAD), with or without enabling pf and ip forwarding.


BTW, looks like a typo, the line in sysctl.conf should be "net.inet.ip.forwarding=1"
