In Topic: Firewall help

07 September 2017 - 03:14 PM




I cannot firewall the PC as i will have 2 wan ports in use on the modem and one will have strict firewalls and the other will have open firewalls, So that when the vessels come into port and can connect via 3g internet connection they can do what ever they need via the internet.


This is exactly why you SHOULD firewall the PC, it's a simple software switch.


You could even get someone who can do some basic coding to make a nice "SAVE DATA!" button in a simple app, and you maintain the block lists for them.


You could use Peerblock and host your own blocklist?!



EDIT: in addition, Peerblock can ALLOW HTTP, and block all other protocols.

So the end user, wouldn't see any loss in "Web Browsing" ability, you'd just block the background apps.

I block "Microsoft" in my blocklist, but allow HTTP and never hit problems.


We have tried to use software in the past but the users have managed to fuck it no matter what, Also if someone gets on the wifi on the boat a software block on the computer will not prevent them from accessing the internet pages. The system also needs to be easily changed over if a new pc is put onboard if its a hardware based firewall it is plug and play but if its software it could be a little more in depth. A few companies have been using software switching but it has not been working out for them and they are also looking into similar setups to us. 


I suspect Office 365 won't work properly or will echo annoying messages if it can't do it's back-to-base bollocks.

I also suspect that it's probably not much extra overhead anyway.  Imagine millions of connected computers bombarding the servers every couple of minutes, I don't think they'd want that.


I tend to agree - try an alernative email client that doesn't do any licence verification.

By overhead do you mean data usage? If so i have done some testing with data usage and have found that over the course of a month office 365 used around 30 Mb of data for its back to base pings, Which on the satellite data costs around $2100 ($700 per 10Mb).

Pretty sure you can't block by program ID at the router level - TCP/IP doesn't include such information and it'd be useless anyway since it could easily be spoofed, you need to do so at the host, ie either the Windows firewall or 3rd party product.  With some routers there will be predefined settings that refer to programs but that's just in a generic sense.


You can use the HOSTS file to block comms to specific sites or IP but that's a global setting.

For Outlook, assuming it's not doing back to base licence verfification, you'd probably only need to allow the ports involved for ingoing and outgoing email.

By default they're usually 110 (in) and 25 (out) for POP3 but fairly sure there's other ports that are sometimes used.  In any case you define such things in the email client so you could refer to the settings there.


Most email clients have the option for periodic refresh/reload so you could set that to 0/off to save data.

In some cases you can download headers only, another way to save.

And if you have ISP level filtering, use that to help stop pointless downloading of spam.

So on the TP link modem i have i can block specific applications, Facebook, Youtube, Twitter, Etc. I need to be able to try and setup the firewalls on the modem to block programs pinging the satellite as this costs data even if it is blocked at the satellite firewall. 

I am trying to prevent Office 365 from sending their server pings out on the specific connection. I cannot firewall the PC as i will have 2 wan ports in use on the modem and one will have strict firewalls and the other will have open firewalls, So that when the vessels come into port and can connect via 3g internet connection they can do what ever they need via the internet. 


Also i cannot have the Satellite and the 3G modem connected to the computer at the same time as this causes ip conflicts and the 2 units both try and act as modems. 


I will try just allowing those ports through the firewall and nothing else to see how well it works, i will also try and setup URL blocking to prevent any other methods of pinging the satellite. 


It is quite a complicated system that i am trying to work out here. 

The modem will be attached to the 3G modem and the Satellite phone through a change over switch where only one connection will be active at a time, And when the satellite internet is activated a timer will start for five minutes then it will switch the connection back to the 3G modem.

Were you using the link in your profile to download the 365 program?
