      My ip config:
      xx.xxx.106.142
      mask 255.255.255.252
      GW xx.xxx.106.141

      When i configure pfsense with it (bitmask 30) i can ping modem (141) but nothing behind him.
      When i use bitmask 2 i can ping some www site. All port are blocked by modem.. When i use bitmask 29 i can ping all and any port aren't blocked.

      I dont uderstand it.. Why it work on other netmask?! And why not work on my mask??

        It should be configured with whatever your ISP gave you to put in.  A netmask of /29 vs /30 changes the network id.

        You also said "When i use bitmask 2 i can ping some www site"…. what is "bitmask 2"?

          When i use /30 (like i get from my ISP) it wont work… (on tp-liink router 255.255.255.252 works well, on pfsense wont work)

            We're missing some details…  So, when you were on your tp-link router was your WAN set to DHCP?  Or are you paying for a static IP block?

            /2???  A mask of /2 would include almost every IPv4 address out there.... you wouldn't be using that.
