pfsense generate icmp traffic to exteral router

Summer

Hi,

I've noticed this row on the pftop utilities, but cannot figure what's the meaning:

pfTop: Up State 1-1/1 (1022), View: default, Order: bytes
PR        DIR SRC                           DEST                                   STATE                AGE       EXP     PKTS    BYTES
icmp      Out 192.168.1.10:27925         192.168.1.1:27925                   0:0            01:35:04  00:00:09    45516  1319964

SRC is the pfsense box
DST is the provider router

Why there's this traffic? Is it safe ?

Thanks, BR
