plz make lan gaming working!!! plz~ I am begging you all~

I just downloaded the Smart's ver. of this game.

But never get the sv_lan 1 command work

(I mean I type the cmd but that doesn't make the lan-play work.)

I watched a TUT from youtube. that TUT told me to use the "sv_lan 1" cmd

tried from 2 pc but none of them worked, I used to play RUS ver. of csgo. It's LAN-WORKING and cracked server working

Net enviroment:

                             PC1

                           /

D-Link router ---

                           \

                            PC2

that's it ... so....

Is that now Smart's crack doesn't support LAN-GAMING? Or I got something wrong?

plz help me, I am begging you guys plz~
