The basic question you need to answer for us is: how is your system doing DNS? Are you running your own DNS server on the router and using it to do DNS directly (i.e., starting at the roo servers and working down)? Are you running a DNS server that uses your ISP's DNS server(s) as forwarder(s)? Are the clients on your LAN using the ISP's DNS servers directly? Something else?
As a general matter, if you want to be able to access the Internet using FQNs (and not just IP addresses directly, something nobody does), you need to allow *some* UDP traffic from port 53 in. Otherwise, off-LAN DNS servers will be unable to respond to the queries you send them ... and while I don't know from what you sent *how* you do (off-site) DNS queries, you must be doing them *somehow*. It would not surprise me if the "current connections" you list below were incomplete DNS queries. If so, the reason "no one on the homenetwork can connect to the Internet" may be that you have an undiagnosed DNS problem, so URLs (or FQNs for whatever services you mean by "connect") do not resolve. The mere existence of open connections should not prevent LAN users from accessing the Internet (at least not in in the quantities you report ... you are in no danger of running out of ports). You might want to report with a more descriptive trouble report. The "SR FAQ" link below will help you do so, if you care to try this approach. (I don't recall your prior postings, but if you really got no responses, it may be that they were too vague to elicit anything useful. There are enough of us regulars, with a wide range of expertises and tempraments, that it is rare that no one responds to a query.)
