I have a Linksys Wireless router with ZoneLabs Integrity firewall from work. Should I be concerned? How can I tell if the firewall is enabled? I went into the gateway address to see the settings, but the only setting showing were those if you had Zone Alarm and PC-Cillin.
Here's one from Symantec.
Some practical notes on this, lifted from another forum:
To verify the vulnerability:
1) Obtain the WAN IP address from the Router status page.
2) Surf to that address using your favorite web browser (make sure that the browser hits the local network - i.e. no proxy, or AOL browser, etc). Because of ISP blocking, I suggest doing this from the internal network.
3) If the administration password prompt appears, the unit is vulnerable.
Users should take the following action:
1) Assign a strong password for the administrative function on the unit. A strong password consists of a random string of letters (mixed case), digits, and, where possible, special characters. This is important to do with all models and all brands. Many users install broadband routers while leaving the default password in place which is a huge security hole.
2) On the router administration page, under the Games tab on the WRT54G (elsewhere on other units), turn on port forwarding for ports 80 and 443, and forward the traffic to an unused IP address. The units are usually configured to start DHCP addresses at .100, so using 192.168.1.50 should be safe in most cases.
3) There are some reports that units were shipped with the firewall disabled by default, so while the users are logged in, they should verify that the firewall is active.
4) Monitor the Linksys website and apply a firmware upgrade (which is hopefully under development) as soon as it's available.
