[ale] Tomcat Monitoring



Can't help with residential. Things are different there.

I have a static /29 on biz and treat their router/modem like a
bridge/gateway.  MY router is setup for the public /29 subnet. No
double-NAT at that layer.

Their router is my gateway with a single address. Put a non-secured,
cheapo, wifi router into one of the comcast ports, it gets a 10.x.x.x
DHCP address and works for guests.

I suspect the tech was right. Disable DHCP and the firewall on the WAN
side.  For common things, the techs are usually right.
