Juan, This is really off topic for this list, but it sounds to me like whatever computer is using that IP is probably also running a firewall that is blocking everything, even ICMP. At this point, you could narrow down which machine it was using a managed switch if you have one. You could also visit the machines and manually look at their IP addresses. The other option (and one I'd choose) is to block all traffic from 192.168.1.147 at the firewall and see who comes to you to complain about not being able to get on the internet.

(1990's hardware can handle 70 users with modest throughput), but if you are curious - what are your specs? I was more wondering if you had a couple machines with malware that may be pegging out your connections state table, or some P2P users. Check your state table and make sure it isn't maxing out. And make sure if you have P2P users, that they aren't maxing out your bandwidth. Blank MTU in your config is fine - that means it will be at 1500 - which is the standard on most connections (at least in the US). You didn't answer if all was well when bypassing the pfSense box. If it is, then start segregating things. Try it with JUST your machine -> pfSense -> Modem, and see how that works... this is granting your box is malware free :) - if in doubt, grab an Ubuntu LiveCD (or variant) and boot it up on your machine to test. Good luck! -Tim -----Original Message----- From: Juan Rivera [mailto:[email protected]] Sent: Monday, April 13, 2009 12:57 PM To: [email protected] Subject: [pfSense Support] RE: [SPAM] RE: [pfSense Support] RE: [SPAM] Re: [pfSense Support] RE: [SPAM] Re: [pfSense Support] website browsing Yeah just called my ISP they are checking on the modem to see if there is something wrong with it as the MTU was blank before I made any changes to it, now it got me thinking I have more than 70 computers connecting to my free BSD you think it can't handle that many ? -----Original Message----- From: Tim Dickson [mailto:[email protected]] Sent: Monday, April 13, 2009 2:54 PM To: [email protected] Subject: [SPAM] RE: [pfSense Support] RE: [SPAM] Re: [pfSense Support] RE: [SPAM] Re: [pfSense Support] website browsing Sounds like you are pulling at straws here - but try and find out what the root of your problem is. If your packets are fragmented, then yes this will slow things down - but it could be totally irrelevant to your issue. If you bypass pfSense is everything fine? How do your traffic graphs look? (how many connections are you doing - check the state table) If it is in fact your MTU - check with your ISP on what your MTU should be, you'll want to leave it matching theirs as changing MTU will just cause MORE packet fragmentation where it isn't necessary, or causing more packets with less data. And if your MTU is correct, your traffic is minimal, and you are still having latency issues start a trace and find the routers your traffic is passing through. Then test the MTU levels to each router to find out which router is causing your fragmentation. You should then point your ISP to that router. The random MTU guess isn't going to get you anywhere. Just my 2cents though... -Tim -----Original Message----- From: Juan Rivera [mailto:[email protected]] Sent: Monday, April 13, 2009 11:12 AM To: [email protected] Subject: [pfSense Support] RE: [SPAM] Re: [pfSense Support] RE: [SPAM] Re: [pfSense Support] website browsing ok I've done that but still the internet slow the MTU is not at 1400 but internet slow is there anything else that could be the problem -----Original Message----- From: Gary Buckmaster [mailto:[email protected]] Sent: Monday, April 13, 2009 1:28 PM To: [email protected] Subject: [SPAM] Re: [pfSense Support] RE: [SPAM] Re: [pfSense Support] website browsing This is not the way to do this as the configuration will not survive reboots. You can set the MTU on the interface configuration page for your WAN interface in the webGUI. I would encourage you to check that out.
