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"?

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.
