Hello.
My ISP somehow blocked my MT router. So I can't use MT router to share internet between computers anymore. I wanted to know - how did they do that? Maybe I should change anything in MT configuration to let ISP know that that's not router, but standart PC?
Lan is still working - I'm able to ping my neighbours from router (via Telnet), but when I try to ping something outside (google.com) - it doesn't work.
If I plug Lan cable in my laptop - internet works fine. I use DHCP client on router and laptop - so there is no mistake in IP configuration on MT router.
Yes, and btw, ICS is not working anymore too.
So, any solutions?
Thanks a lot.
router is NOT a PC - sure you can install it on PC, but it is still a ROUTER not an ordinary PC.
firewall allso can be installed standalon on PC but that will not be PC - it is firewall - all it does is filter junk out of your datastream.
BETTER talk to your ISP and ask if they would be happier if you used some EUSSO or DLINK or whatever wireless AP.
and again - router is not a PC.
go and talk... better do not mess with network infrastructure of you ISP and makeit right by talking t them

Thanks for answers, guys.
As I just said - if I plug LAN cable in my laptop (MAC addres is same with router's MAC address, IP addresses assigns by DHCP), internet works fine.
ISP 100% has put some kind of filters or something like that.
I accent that ICS (internet connection sharing) is not working too. Before it was OK - my router was able te get out to WAN and ICS was working fine too.
I checked my configuration again, but there just can't be mistake, because I did not even touch it - internet just stopped to work.

Is the IP address they assign a reserved IP address like 10.10.x.x or 192.168.x.x? If so its possible they are doing NAT several times and when you NAT the final time it breaks, you can only have so many NATs occuring before it breaks.Thanks for answers, guys.

It is also possible if they are assigning the same extenal subnet as your using on your internal. 192.168.0.x for example to you and your using 192.168.0.x for your internal it would also cause your same issue. If both the WAN and the LAN have 192.168.0.x for example then it couldnt route outbound, it would route to itself. A trace route would reveal such a loop, if you post your traceroute it would also help. From your PC and from the Mikrotik.
Another thing to check if they are giving you a real internet IP:
Log into the mikrotik, verify the DHCP client is receigin similiar IP address, subnet mask and gateway, if so try pinging from the mikrotik to the real world. Write down some real world pingable addresses from your PC before hooking the Mikrotik back online to try this.
Without seeing your config further help would be difficult without more information.

Did you verify ethernet port your using for WAN can talk to your laptop when plugged directly into the WAN?MAC, IP, GATEWAY, NETMASK is correct in MT router's configuration!
I'm using MT router for about three years, I'm not beginner in network configurations. I never had such problem with it. It worked fine until one day... I'm confused.
I don't mean verify the MAC, I mean change it... to see if they are blocking it based on your nic's MAC address.MAC, IP, GATEWAY, NETMASK is correct in MT router's configuration!

interface ethernet> print
interface ethernet> set 0 mac-address=aa:bb:cc:something:different
then try again ... if that's not it then they are probably checking TTL value and dropping stuff from behind you.

OK,....OK,...OK.!!!
i am beginner since almost 9.5 years ago in networking, when you aren't beginner i thing everything should be without more idle time and sure the problem is not in your Mikrotik's Box, and just claim to your isp why...and...why blocked or try other isp. easy to answer...
i think your problem is strange insident, not-beginner should not confuses. i am support you.
please repost and close this topic when you have solved
