Hello.

During connect to provider, he authenticates me successfully moreover I got public ip but can not ping anything.

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 8.8.4.4, timeout is 2 seconds:

I'm able ping outside ips for example public DNS server (8.8.4.4) only using extended ping like:

gate#p
Protocol [ip]:
Target IP address: 8.8.4.4
Repeat count [5]:
Datagram size [100]:
Timeout in seconds [2]:
Extended commands [n]: y

Type of service [0]:
Set DF bit in IP header? [no]:

Data pattern [0xABCD]:

Sweep range of sizes [n]:
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 8.8.4.4, timeout is 2 seconds:
Packet sent with a source address of 192.168.172.1
!!!!!
