Configure Squid in IVS Environment

End Result: A proxy server performing web-cache sending outgoing data from modem/DSL and
geting incoming data from satelite.

Scenario:

Proxy Server: linuxbox5
Proxy Server Port: 8080
IP address Assigned by ISP: 210.56.5.22/255.255.255.252
IP Address Given by Satelite Company: 64.32.5.88/255.255.255.252
Internal Network: 192.168.0.0/24
Number of NICs in Proxy Server: One

Assumptions:

1. Proxy server is connected with ISP and 210.56.5.22 is assigned as primary IP address to proxy server
and 64.32.5.88 is asigned as secondary IP addres to proxy server.
2. Proxy server’s gateway is configured as provided by ISP, so outgoing trafic go out using ISP
(DSL/Dialup).
3. Satelite interface card is instaled and configured and sync.

Perform all steps given above under the heading “Simple Web-cache Setup with Squid”. And do the
additional steps given below.

# vi /etc/squid/squid.conf

Add folowing lines in squid.conf file.

tcp_outgoing_address 64.32.5.88
udp_outgoing_address 64.32.5.88

Save and exit and start service.

# service squid restart

Checking: Instal ipterf package on proxy server and monitor packets on satelite interface
