Ensuring i don't make noise on WAN?



  • Technician has just been to my house to make new setup so that I can connect directly instead of being behind ISP router, etc.
    He told me I better damn make sure I don't create too much noise otherwise I will be kicked off for an hour, etc.  Not changing equiptment/MAC 3 times in a row. That he knows because he tried himself in private.
    He wasn't too fond of Pfsense either it sounded like.. He has me all worried now.  :o

    What do I need to check and be sure of settings-wise, so that I don't create "noise" (What this exactly is to me is not fully known).

    In my mind all will be ok ?
    1# DHCP gives my WAN interface the one adress i am assigned and I will continue to do so. Default it will just work out, it won't continue to ask for IP..
    2# I have deleted the default rule on my LAN side that let's anything from my devices thru and put in only very few common ones so far. (With the exception of my Phillips Hue Bridge, which is allowed all)

    What could my Pfsense possibly do to mess things up?.

    "Not changing equiptment/MAC 3 times in a row"

    What??  Its your equipment if you want to change the mac 100 times a day what the F should they care for??

    If your on a cable modem you would have to reset it when you change the mac anyway.

    I could see where they might have a problem if you were spewing out dhcp requests 10,000 an hour or something..  Maybe they don't like the ping once a sec to their router? ;)

    To be honest the guy sounds like your typical installer idiot.. They know what signal strength should be there and how to adjust it - but when it comes to actually network not a clue.. When the installer was just at my house he saw my grateful dead stuff on the wall in my computer room and we got to chatting and asked what I do.. Anyway I mentioned mpls and lot of our customers switching to sd-wan, etc. and he just looked at me like a deer in headlights.. Not a clue to what mpls even was or what sd-wan meant, etc.

    So not so sure I would take networking advice about "noise" from the guy that serves you your fries (cable box) with burger ;)



  • To be honest the guy sounds like your typical installer idiot..

    My thoughts too.  Those guys tend to be the ones that also run in the cable, doing a lousy job in the process.  They are not hired for their networking knowledge.



  • You should do absolutely nothing, the guy clearly has no idea what he is talking about. If he can't understand that what he calls "noise" isn't any different than normal traffic from your system to the internet he shouldn't be in his job at all.

    I actually liked the guy a lot :P, knew way more than me. We talked a lot about things, sounded like he liked to play at home a lot too. 10x times better than those I talked to on phone in tech-support..  But not sure who to believe anymore…  Tech support told me that once i connected to their new router id get forwarded public IP to my gear.. installer laughed and said that it be impossible... that actually the old box was capable of that, but the new wasn't.. but now he had to put new one up since he already took down the old..

    Maybe I said the wrong thing, he clearly meant traffic noise... requests, TCP.. etc. And if my devices got infected and sent out crap.

    Anyway, I will try to hook Pfsense up directly to modem a bit later, when I read manual of new router..  if it's really true it can't bridge.. forward, or something.
    Because there is a bit of problem... he said I needed to go thru the router otherwise I couldn't have voIP..  So if all is true, it's either being free of that router or having voIP and not being free of their router..

    What device did your isp give you? Make and model number?



  • I actually liked the guy a lot :P, knew way more than me.

    He may have been a nice guy, but that doesn't make him an expert.  I've been in the business for 45 years and in that time I've met a lot of "experts" who really haven't a clue about what's going on.  Not too long ago, one guy tried telling me that the NIC bandwidth (100 Mb, Gb, etc.) is determined by the NIC detecting the cable type (CAT 5, 6).  I almost decided to go get my shovel!

    The installers hired by the cable and phone companies tend to be little more that warm bodies, whose responsibility is to run cables, install the equipment and hope it works.  They're about as expert as the store clerks in Radio Shack, Best Buy, etc..

    "They're about as expert as the store clerks in Radio Shack, Best Buy, etc.."

    Hahahah…. Oh this so true... Luckily have not had to go to a best buy in a long time.. I always just cringe at the nonsense they spew to customers..  I couldn't keep my mouth shut one time and ended up having a line form asking me questions ;) hehehe

    And NO I do not want the extended warranty on this $50 item!! ;)



  • I always just cringe at the nonsense they spew to customers..

    On one occasion in a Radio Shack store, I overheard a clerk tell a customer that a computer floppy disk drive wouldn't work in Europe, because they had a different power line frequency there!

    On another occasion, in a Future Shop store (they were bought by Best Buy a few years ago and are now gone), I heard a clerk tell a customer to buy Monster cables.  I then showed the customer the rack of generic audio cables and told her that's all she needed.  For some reason, the clerk was annoyed.  ;)



  • @johnpoz:

    Not sure if you will know it, since we could be from two entirely different places :), and thinking it could be specific to here (Denmark)

    Make/Model:  Tilgin HG2381  (Or, "HG2381_EU" )

    So far I haven't found a really detailed manual myself, mostly short ones provided by ISP's, and their about portforwarding only.
    I am not totally familar with what id be looking for… but I heard about "Bridge mode" or putting in DMZ..  I did find page in settings where it said something about operation mode, but it only had one option, which it already was in.. and DMZ section seemed weird..  Also been looking for anything that could disable firewall, etc.
    Then there was some other settings I didn't quite get.. i'll get a screenshot of it.

    Right now I am connected directly to modem, and all seems fine. Finally I have been able to open up for Plex to the outside for example.

    Haha okay, even I could say that that is not really correct.

    But I think he knew his stuff.. started since 1996.. took some certificate that cost 13500Euro he said.. then CCNA.. Been installer and worked in IT department…  talked a little about VLAN, subnetteting, etc.
    And about how I also bought CCNA book in curiosity (but totally lost in sections).
    I was a bit surprised because I know installers often don't know more than just installing, and they be like "Don't ask me".

    But of course, he can be wrong, and not up to date with everything... or who knows, a small bias in some things because he is from the ISP company, and what he likes himself the most.



  • ^^^^
    Well, it would be nice to know what he means by "noise".  On the WAN side of the firewall, there will be things like DHCP requests and ARP requests.  On IPv6, there will be neighbour and router solicitations.  All of these are essential for the operation of IP.  Of course, there will likely also be user traffic, stuff like web sites, email and more.

    True.

    He said that even some off-the-shelf known brand routers would be kicked off.. because.. noise..

    That's the first I've heard of that one.
