hi, I've just installed an 834n router and dont know how to set up the outgoing firewall. can anyone advise me please?
This is the rangemax router, right? (adsl/cable)
Yes, the 834 N.Is it complicated to do?
Outbound firewall being... Outbound Services??
Netgear DG834 series firewall setup is very easy... The default is to block all inbound unless it is a response to an outbound request, and allow all outbound.
I have mine setup to block some outbound traffic, and some impond ports that don't seem to be blocked by Netgear's definition of 'ALL'!!
What exactly are you trying to do (the user guide is quite good with respect of how to configure the firewall.
Basically you first create a 'Service' entry with the port & IP info and then use that service in a firewall rule. There are a few built-in service entries for you to use 'out-of-the-box.
Try to make each and every day the best it can be.
I'm just trying to be as security minded as I can and learn whilst I'm doing it. Do I need to block outbound services if inbound are secure, according to grc.com.
can you tell me which ports netgear firewalls do not block?Originally Posted by EtheAv8r

Blocking outbound ports is generally done if you want to restrict the type of traffic leaving your network (from your users), such as disabling gaming ports.
Most home environments wouldn't normally need to change the defaults.
Blaster, Bofra/MyDoom, Bagle, Yanz et all all took advantage of unpatched vulnerabilities and then went out through fixed, known (otherwise unused) open outbound ports.... and most infections were home PCs/Home networks, so blocking those few specific outbound ports was (is?) IMHO worthwhile as it only takes a few seconds to do. Plus I also always block Ports 135, 136, 137, 138 & 139 outbound as they have been utilised in a number of attacks and I only want these in use internally on my network.

Better still, install Zonealarm (free version) and gett authorisation for ALL external requests outbound from you PC.

Netgear dont recommend software firewalls with their routers.
I use one as do the majority of people who want their PCs as protected as possilbe. A software firewall will trap outgoing as well as incoming nasties!
