Some very simple questions, not just for me! I have two home laptops at home at the moment, usually one is switched on at a time to connect to the net (via the same wifi modem), but I have had both connected to the net at once on occassion. So being able to connect both to the home wifi internet would be helpful, without any comodo issues. I am installating comodo firewall on both for simple home wifi internet browsing.
Setting up comodo for the first time:-
1 - When comodo firewall finds a new network, is this essentially and most likely comodo firewall finding my home wifi (which is always on), or would this ‘found new network’ message pop up anyway even if my wifi was not on - would the message appear on comodo first installation anyway to simply set up my pc, even if a wifi or network device wasnt switched on and in range?
2 - Is part 1 of ‘Step 2’ in comodo firewalls installation (to be fully accessable to other pcs in this network) absolutely necessary to click in order for more than one home device to use the same wifi internet adapter at once? Or is it only for home file sharing from one system to another, eg via wifi (which I would not use)?
3 - Im guessing part 2 of ‘Step 2’ (do not detect any more new networks) is obvious not to check, if I do not want to use any other wifi or network devices?
or would this 'found new network' message pop up anyway even if my wifi was not on -
It might still find a new network according to the static or dynamic ip settings of an alone computer.
The only way not to get fooled in my opinion is to previously assign static ip (of course in the same workgroup and ip range).
Is part 1 of 'Step 2' in comodo firewalls installation (to be fully accessable to other pcs in this network) absolutely necessary to click in order for more than one home device to use the same wifi internet adapter at once?
Strictly speaking, it is only necessary for each computer to access each other; but in order to stay connected, each computer needs to access the gateway in the same workgroup, so you would better allow it.
No one keeps you afterwards from forbidding shares by writing blocking rules for the netbios ports 137-139 and the concerned ip.
Whatever the situation is, if you have no windows share, you won't be able to access whatever on the lan except seeing the existence of other computers itself.
do not detect any more new networks) is obvious
Still strictly speaking, if you want to customize the LAN rules, you don’t need the wizard, it’s enough to write the appropriate allowing and blocking firewall rules for netbios.
I dont have anything to share between both machines, I just need browsing to work on both machines at once, nothing else.
Do I definately need the “fully accessable” option ticked, in order to stay connected, with more than one system, for simple web browsing at the same time on both machines? When you mean “strictly speaking its only for sharing”, do you mean that web browsing may work on both machines even if the access option was off, but other connections may not, eg multiplayer gaming using both home systems, as an example? Im not sure if I understand 100%
The other question I forgot to ask was if my wifi modem was ever switched off, that it may lead to comodo ‘finding a new network’ each time it was switched on again, if its address kept changing automatically? If the address does change each time it is switched on, will I still be able to connect to the same original saved wifi?
When i speak of “sharing”, it is of sharing local computers (including gaming between both of them).
All of the internet connection shall work from either of the computers considered as a standalone one whatever option you choose in the network discovery and the ports wizard; however, more restricted options (stealthing) would lead you to write specific rules in order to get p2p or gaming to work (such rules are documented for several p2p and games in this forum).
The network discovery allows you to define a specific LAN zone you are then able to specify in a peculiar firewall rule (e.g. and when speaking of file sharing, saying that netbios is safe over the LAN zone but unsafe outside).
Remember that, not relevant of the fact you want to share both computers or not, you shall be alerted for local communications between the two computers: it is therefore better to make an appropriate LAN zone blocking or allowing depending of your choice in order not to be alerted all day long for these communications.
Don’t confuse the LAN and WAN ip of your modem, the network discovery concerns only the LAN side; but switching the modem off and on could maybe change the LAN ip range, altough it most probably would stay in the 169 range.
If wanting to 100% avoid such a situation, you should disable DHCP and assign both your computers a static LAN ip in the 192.168.x.xxx range.
