Hello !
I pinged gw from opnsense and saw :
Host is down.
Then I added entry to arp table with gw's interfaces.
After this one I see error : ping sendto no buffer space available
I don't know how to fix it. Please help me with that

There's a comprehensive troubleshooting guide from pfSense regarding this error:
https://doc.pfsense.org/index.php/No_buffer_space_available
I'll consider it to be a starting point for further analysis/debugging.

Thx for link.
I want to ask is this parameters ok?
netstat -m output:
vmstat -z | grep mbuf output:
I forget to say that i use VMware Vsphere , pciconf :
Also , I added:
echo 'kern.ipc.nmbclusters=524288' >> /boot/loader.conf
echo 'kern.ipc.maxsockbuf=1048576' >> /boot/loader.conf
echo 'hw.e1000.rxd=4096' >> /boot/loader.conf
echo 'hw.e1000.txd=4096' >> /boot/loader.conf
and
net.inet.tcp.sendbuf_max=16777216
net.inet.tcp.recvbuf_max=16777216
net.inet.tcp.sendbuf_inc=16384
net.inet.tcp.recvbuf_inc=524288
