LnS and Voyager 210 Router

I cant understand why it is stated so often that LnS is not set up for working with a Router.

I have a BT Voyager 210, and LnS seems to work ok without all the complicated settings talked about elsewhere here. I only have a single PC, but use the router for the added protection of a hardware firewall.

I use P2P which works ok with the added torrent rule. I just interested to know why it all works without any added messing about with router rules.
All this talk about adding router rules could put some people off from useing LnS.

 

Hi Delgado

Unfortunatly, Routers are not created equal, and in some case IGMP and UDP packets must be handled by routers rules.

Your router is working well with no special rules: That's fine !

What is the rules set you're using?
and
Can you show us a sample of your log (I mean a significant sample of the log showing all rules if they are applied...).

Thank you.

 

Hi

Thanks for reply-I will sort something as soon as I can. Ive been offline for a bit, as i changed ISPs.

Just managed to sort out my connection. When I sort out my Router again will go into this further.

I normally use Advanced rules set and sometimes Phantoms Rule set.

Hi Delgado

Okay: let us know if there's some problems with your setup with the new ISP.

Please remarks that some ISP provide to their clients a modem-ROUTER not only a "simple" modem (but they don't always tell this to the client...)

If it's the case, you'll have 2 router instead of one (yours and the one of the ISP), if so, this may be a little bit tricky...

The best is to aks before to the ISP support to know what kind of modem they installed and if your router works with their device...

 

Hi

Further to my original post, in answer to the question of my ISP installing a modem; this did not happen because im with Virgin via my phone line. I cannot get cable where I am.

As stated, I have a Voyager 210 only connected to my PC; no other PCs connected.

The more I go into this, the more confused I get-it all works with LnS, although I did have to allow ICMP type 3 to get Windows Live Messenger to work.

I see lots of entries in the log relating to Voyager Home and UDP:BooTP/DHCP with the option to allow Port 1900. Whats all this about?

I cant seem to work out how to post a copy of the log!

 

Hi Delgado

Okay and this device is a router: right?

ICMP Type 3, code what?

For Windows Live Messenger ? This program used TCP protocol and makes connection to the remote ports 80 (Http),
443 (Https) and 1863 (Messenger). This is for the basic functions of chating ...

For Voice, Video, file transfer and so on other ports + UDP are used.

Entries in the log: allowed or blocked ?

DHCP is the protocol used to obtain an IP address from the DHCP server, (from your router...).

You have only ONE PC with that router. Did you have a fix addr. or what?

Port 1900 in UDP is the SSDP service in windows...

 

Okay and this device is a router: right?


Yes it is a router.

ICMP Type 3, code what?

Code 4

You have only ONE PC with that router. Did you have a fix addr. or what?


I have a fixed address of 192-168-1-220

I forgot to mention 192.168.1.1 is my router

Attached is log of about 3 hours

 

Hi Delagado

This is UDP packets uploaded from your PC
To port 6881: this a the "standard" BitTorrent" port...

This is incomming UDP packets uploaded from your PC to a broadcast IP addr.
related to the SSDP windows service.
Stop this service if you don't need it Or authorised these packets..

Same things here except they comes and go to the same port 1900 in UDP now downloaded from your router.
Did your BitTorrent used this option? I can't guess that...

Check in your BitTorrent program and disable the SSDP or UPnP option and check the result...

ICMP type 3 code 4= Frag. Needed but a Flag DF is enabled.
Needed with some network connection...

 

Hi Climenole-

Thanks for information-all seems to be working OK!
