In a command prompt, type

ipconfig /all

and see whether this is a DHCP-assigned address. It should tell you what the
IP address of the DHCP server is/was, if so.

You don't have a static - you have a private IP. Something is doing NAT.

Ah. Why do you have two NICs? Disable one. Are you using ICS? Don't.

I suggest you get yourself a decent, inexpensive broadband router firewall
appliance (Netgear, Linksys, Dlink, etc) and stick it betwen your DSL modem
& network/computers. Let it do DHCP and NAT. You don't need to install any
klugy ISP-provided software on your computers that way. I never do...

That said - there are two issues here, it seems. You stated that you were
having problems with others connecting *to* you. What do they need to
connect to, and how, and for what purpose?

Get your internal network fixed, your internet connectivity cleaned up &
working, and *then* deal with inbound access to your network from the
Internet.

Well, perhaps, but I don't know which particular deity is responsible for
troubleshooting TCP/IP connectivity issues, so it's probably not relevant
here.
