[KLUG Members] Refurb IBM High Rate Wireless Gateway

[Peter Bart]

Hello All,
The dumb question I have today is about the built in firewall on the 
refurb unit I bought from itxchange. Following are selected excerpts and 
the unit is probably about 3 years old. How safe am I behind this and is 
there more configuration I need to do besides the standard setup? There 
are a ton of settings under the advanced tab and yes, for those of you 
keeping track is does work with Linux. More on my adventure with SuSE 
later. I'm still trying to get it to talk to my dsl line and slowly 
configuring it. The basic install was a breeze, it just didn't see my 
internet so no automatic updates yet.
Thanks,
Peter

> Built-in firewall: The IBM High Rate Wireless LAN Gateway has a built-in
> firewall to protect the computers on the local network from hackers on the
> Internet.
> – NAT: NAT hides the IP address of the local network from the Internet.
> – Packet filtering: Data packets without a trusted IP address or port are
> dropped. For DMZ, the exposed computer receives all packets that would
> otherwise be dropped.
> – Stateful inspection: Data packets are inspected for relevance within 
> a data
> stream or session. If the data packets are not relevant, they are dropped.
> For DMZ, the exposed computer receives all packets that would
> otherwise be dropped.


> Wireless access point: The IBM High Rate Wireless LAN Gateway contains
> an embedded wireless access point that supports the industry standard
> (IEEE 802.11b WLAN) protocol with a data rate up to 11 megabits per
> second (Mbps), can have up to 63 simultaneous users, and is compatible
> with all WiFi IEEE 802.11b-compliant wireless LAN (WLAN) client cards
> with seamless roaming between access points.

> Wireless security: As access control mechanisms, the IBM High Rate
> Wireless LAN Gateway has ESSID for wireless network segmentation, MAC
> address registration, and wireless equivalency protection (WEP) (64- and
> 128-bit) encryption.

> Dynamic host configuration protocol (DHCP): The IBM High Rate Wireless
> LAN Gateway provides IP address acquisition and management.

> Virtual Server: With the IBM High Rate Wireless LAN Gateway, you can set
> up a server on your local network that can be remotely accessed from the
> Internet (an ftp server, for example).
> v DMZ: The IBM High Rate Wireless LAN Gateway can support some special
> applications and Internet games. With DMZ, one designated computer is
> removed from behind the built-in firewall and exposed to the Internet. 
> This
> speeds up Internet gaming and might be required from special applications.

> Virtual private networks (VPN): The IBM High Rate Wireless LAN Gateway
> supports the following VPNs:
> – IP Security (IPSec) passthrough
> – Point-to-point tunneling protocol (PPTP) passthrough
> – Point-to-point protocol over Ethernet (PPPoE) for DSL
