Hello mikrotik guys!!
Can you upload script with blocked virus ports from demo router to forum or somewhere else.I can`t login via ftp to demo router and demo user haven`t write priviligy...
Before few months I was already put on forum full code ... only seach on forum ...
anyway here is again code:
Just copy and paste ...
anyway here is again code:

[quote="gianluca"]I suppose that p2p programs (like emule or edonkey or bittorrent) can also use these ports so that blocking virus like that can also block the peer to peer program.
any experience on it?[/quote]Yes, that's true, but p2p programs select these ports randomly, and if the port is firewalled, they simply try another one. So, blocking some of these ports wouldn't affect operation of p2p programs.

Got a question for you. Is it possible to get the IP or MAC address of the computer that it finds the known virus on? We only use static ip's for our customers so we would immediately know who it came from and can call or email them informing them a possible virus has been determined from their system.
Hi, Marvin
The easiest way to do this is turning on logging on the firewall rule, that filters unwanted virus activity. Or you can create a forwarding rule for any specific part of traffic with "passthrough" action, and turn on logginig on it.
Be carefull if you do this from winbox on a heavy loaded system. Catching a pair of thousands of packets within some seconds, when the log window is open, can hang your router. Turn logging off before opening a log window.

we are thinking about a deeper solution:
pass all the traffic with a rule called virus (that checks all viruses with the rules here explained)
we also limit the maximum connection per src-address to 120, so if a virus is opening a lot of connections this fill the connection and the customer cannot use the internet.
if a virus is found for a certain IP address we would like to redirect the user to a local web page that says: attention, you have a virus.
extra function can be to have the name of the virus (if we know the rule that blocked the traffic) and also have the pacth of this/all virus downloadable from this page.
is there someone with good ideas on it or that would like to collaborate to such a solution ? we can set up a team and create this very added value solution for the residential market customers.

Three questions about timew's filter set
1) In the chain=forward set, the 4th rule does a jump to the virus chain. As the virus chain does not have a return at its end, how do the remaining 3 forward rules ever get tested? (udp accept, limit pings, drop excess pings). I don't see how the chain ever gets back to those rules.
2) In the chain=input section, rule 4 also does a jump to the virus check chain. How can the actual router itself successfully be attacked by a virus/worm? Does the actual router really need protecting by this chain?
3) The last rule in the chain=input section states in the comment that the rule will log and drop everything else. But the action on the rule is accept. Shouldn't it be drop?
Thanks for helping me learn!
