The W11 has an interesting mix of routing capabilities. You can
forward up to 64 ports or port ranges ("pinholes"), but the
mappings are static, i.e. triggered
maps are not supported. You currently can't do any
port filtering to control the services that users can access, but Cayman
says they'll be adding this in a future firmware release. You
can also set one "default host" that is effectively placed
on the WAN side of the firewall.
If VPN is your interest, you'll find that the W11
supports pass-thru for multiple PPTP or IPsec client sessions.
There's no hard limit on the number of sessions or number of sessions
per server. On the downside, "pinholes" won't
work for accessing PPTP and IPsec LAN-side servers from
the Internet (WAN), although you can try using the "default
host" function for this.
Up to 16 static routes are supported, and you can
enable RIP1, RIP2, or RIP2 with MD5 authentication for dynamic
Logging is restricted to configuration "console"
type messages, with no Web site or other IP traffic logged, and
no security ("hack") attempts. Cayman says that "a
soon to be available product" will provide security event
logging, though. You can clear the log, but can't save it
or send it to a syslog or SNMP trap server. Other links
on the Monitor page let you view a variety of router and network
The W11's routing features include a few that you
don't normally find in a consumer router, but that a BSP would
feel right at home with: (These features are available via the
Telnet admin interface only.)
You can enable bridging of non TCP/IP
protocols (such as AppleTalk and NetWare) between all router
interfaces (WAN, LAN, and Wireless). Bridging essentially
makes multiple networks look like one network by not paying
attention to IP addresses, but using devices' MAC addresses
to send data to the right place. (See this
page for more on bridges.)
The "Traffic Shaping" option
lets you set the maximum transfer rate (throughput) that's
allowed through the router. This setting applies to
all traffic through the router, i.e. you can't set it on a
per-user or application basis.
