Hi

The following are the step wise tasks for this requirement. I am happy to help you with the configuration part also.(I would like to suggest you to use a Private Range IP in the Branch Office instead of 192.100.1.0/24. range)


1) First you can set up a IPSEC tunnel between your ASA5510(192.168.100.2) and the TZ-170 Sonic Wall(192.168.200.2)

2) Permit the traffic ' tcp 192.100.1.0 255.255.255.0 host 192.168.20.125 eq (proxy_portno) ' from the Sonic Wall inside interface

3) In the ASA , permit the traffic tcp host 192.168.20.125 192.100.1.0 255.255.255.0 eq 80/8080/443 in the inside interface of the ASA

4) Pemit/configure your Head office Proxy for Branch office 192.100.1.0/24 to have internet access through it.

5) Configure Banch office Users Internet Browsers with the Head office Proxy IP(192.168.20.125) and Port

IE-->Tools-->Internet Oprions -->Connections -->LAN settings
