[OPLINTECH] Cymphonix network composer

[Chad Neeper]

While I'm not specifically familiar with Cymphonix, the system you have 
probably can be made to work better with reasonable effort and probably 
doesn't need to be scrapped. Usually, content filtering can be adjusted 
to meet your needs...either more restrictive or less so. It's all in how 
the filter is configured, so if you're not happy with the current 
results, you likely have the ability to tweak it.

It sounds like you may need to have someone who is familiar with 
Cymphonix...perhaps a Cymphonix tech or the original installer (or at 
least someone you trust who is experienced with firewalls/proxies) 
...evaluate and perhaps adjust your configuration. Have them check your 
DHCP configuration, as Bob mentioned. If it is giving out IP addresses 
starting with "10." or "172.16." or "192.168." to the wireless devices, 
then you may need to reduce the lease time, again as Bob mentioned. If 
it's not giving out IP addresses in that range to the wireless devices, 
then you probably have more serious configuration flaws that need to be 
addressed.

If the configuration and licensing looks to be correctly configured for 
transient users, then it's possible that you may have a bug in the 
software. If you haven't done any software updates to your proxy/filter, 
with two years having passed, it is likely that you're running older 
software that needs updated.

Just some random thoughts,
Chad
