![]() My old Belkin modem/router was simple enough for me to run a nice little home LAN. Since then I've had ISP supplied hardware, the latest of which, had a minimal GUI. So I got my own separate modem and router. I'm now accessing the Internet consistently at a good speeds, so no complaints there. It's just that when I look into finer configurations I find it quite confusing. Like 2 DHCP servers, each with different IP ranges? 2 different firewalls. 3 if you include Windows' own. Is it important to have so many, or is it reasonable to turn the modem ones off and let the router handle these things? -- Richard Treen --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus |

It's certainly unnecessary (and maybe undesirable) for you to have two DHCP servers; two firewalls doesn't sound like too bad a plan, in principle at least. But are you sure that your modem is what's doing it? Modems that I've come across are just that, modems, with no other functions in. Could you post makes, models etc for your various bits of kit? -- Henry Law n e w s @ l a w s h o u s e . o r g Manchester, England |

The ISP provided Technicolor modem/router's Telnet config system was daunting. I bought a Linksys WRT1900ACS router then looked around for an ADSL2+ modem. The Draytek Vigor 130 had a reassuring name, so I got one of those. Later I found that there is a bit of confusion over the difference between the "International" version of the Vigor 130, which is said to be a Modem/Router and the UK version which is Modem only. So, I'm less than 100% sure whether the DHCP server which is enabled by default on the modem, is necessary for modem purposes, or is just an obsolete artifact of the Vigor 130's modem/router version. As you suggested, the firewall duplication might not be so problematic. -- Richard Treen --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus |

I've had a quick look at the manuals and, as you say, they're really confusing. One that I saw suggests that you can turn off the DHCP server in the "modem"; have you tried that and if so what happens? -- Henry Law n e w s @ l a w s h o u s e . o r g Manchester, England |

I've tried it turned off and turned on and it makes no immediate difference to internet access quality or speed. I don't know if there'll be other, longer term effects. It's mainly that I have some plans to access my home system while I'm travelling abroad and for these purposes I'm pretty sure that I'll need more understanding and control of the hardware than I currently have. -- Richard Treen --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus |

Well if internet speed is OK and your two DHCP servers aren't getting in one another's way then I don't see that you've much to worry about right now. I'd turn one of the DHCP servers off if I were you; if you're bothered that the modem one is needed for something that's in there then turn off the router one; but you say that it works OK with the modem one turned off and that's what I'd do, personally, because it's untidy, and untidiness in systems administration is never a good idea. I have some plans to access my home system while I'm travelling abroad If I were you I'd think -- and plan -- extremely carefully before doing that. For example, have a look at this: https://superevr.com/blog/2013/dont-...nksys-routers/ It doesn't matter if you don't have a Linksys router of this kind; the point I'm making is that for security you're depending on code that someone else has written, and for consumer-grade kit the manufacturers don't always have the funds to harden their router code properly. -- Henry Law n e w s @ l a w s h o u s e . o r g Manchester, England |

Yes, that was my first concern, untidiness, because there are more enough problems to keep me occupied already. It seems that almost every new move, even the apparently simple ones, brings up a batch of problems to deal with. 30 years of computing so far and still struggling with the details. I have some plans to access my home system while I'm travelling abroad If I were you I'd think -- and plan -- extremely carefully before doing that. For example, have a look at this: https://superevr.com/blog/2013/dont-...nksys-routers/ Thanks, I read that with enough understanding to be horrified but not quite enough to ensure future safety. So, once again my usual level of expertise is available to deal with this one. It doesn't matter if you don't have a Linksys router of this kind; the point I'm making is that for security you're depending on code that someone else has written, and for consumer-grade kit the manufacturers don't always have the funds to harden their router code properly. Now that Belkin has bought out Linksys the future will perhaps look much rosier. Maybe if I spend enough time struggling with the smaller problems the big problems will be completely replaced by other big problems without any intervention on my part at all. Good job it's all such fun. -- Richard Treen --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus |
