[Sussex] Stealth on SAR routers with firewalls.

[Angelo Servini]

I thought this might be of use to the LUG:

Firstly to set up stealth on your router use the instructions given at
www.chrismarsh.co.uk/SAR110. These instructions are good for the 130 as well
as the 110.   It seems likely that all their firewall routers operate in the
same way.

However, I found that port 80 was still "open" according to www.grc.com

To finally close off all the ports do the following:

On your routers web control panel:

Go to "SERVICES", "NAT"
then 
click on "NAT" rule entry
click on "ADD"
select a flavour of "RDR"
enter an id of "20"
set ISNAME to "PPP_0"
leave PROTOCOL as "ANY"
set the local IP Address
	from ... as   "192.168.7.10"
	to ..... as   "192.168.7.10"

leave GLOBAL IP as zeros

set LOCAL PORTS to
	from ... as   "80"
	to ..... as   "80"
	local .. as   "80"

then click on SUBMIT

dont forget to SAVE/REBOOT.

This will then stealth port 80 as it just sends the packets into nothing on
their way out - therefore stealthed.

I hope this is useful.
