Good morning,
I am beginner with sophos.
I project to redirect (through sophos) HTTP requests of LAN Network to the proxy server.
Topology=
External address===sophos====proxy server 172.17.1.14
----------------------------------||--------------------------
-----------------------------LAN Network 172.17.8.0 --------
ip External address=41.x.y.z
Sophos version =9.310-11
Configurations=
Then I did this on sophos web GUI, hoping to redirect all the http requests to the proxy:
1)Network Protection >NAT >NAT
NAT:
Rule Type: DNAT
Matching Condition=
For traffic from :LAN Network
Using service : HTTP
Going to : EXTERNAL ADDRESS
Action=
Change the destination to =proxy-server
And the service to :=Port 3129
Automatic Firewall rule= checked
2)Network Protection >Firewall> Rules
Sources:LAN Network
Services:Any
Destinations=proxy-server
------------------------------------------------------------------------
View rules on sophos CLI
sophos_firewall:/home/login iptables -t nat -L -n -v
Chain USR_OUTPUT (1 references)
pkts bytes target prot opt in out source destination
0 0 DNAT tcp -- * * 172.17.8.0/25 41.x.y.z tcp spts:1:65535 dpt:80 to:172.17.1.14:3129
Chain USR_PRE (1 references)
pkts bytes target prot opt in out source destination
0 0 DNAT tcp -- * * 172.17.8.0/25 41.x.y.z tcp spts:1:65535 dpt:80 to:172.17.1.14:3129
-----------------------------------------------------------------------------
Checking port 3129 on squid server
root@proxyserver-# netstat -tpln | grep 3129
tcp 0 0 172.17.1.14:3129 0.0.0.0:* LISTEN
Sadly, no redirection happens. The LAN Network don't seem to be using the proxy..
Any advice is appreciated!
Thank you in advance.
