Beginner - SRC NAT vs Masquerade

Hello,

The default configuration on my routerboard is as follows:

chain = srcnat
out-interface = ether1-gateway
action = masquerade

Should I change this to action = src-nat?

And in the To-Addresses, should I put in 10.0.0.123 (<- My static IP from my ISP) ?

I remember reading somewhere that src-nat is faster if you have Static IP.

Masquerade will use out-address automatically, src-nat will use only one specific address.
There are no any visible performance issue, when masquerade is compared to src-nat.
For 99% of installations, action=masquerade will perform with great results.

Thank you.

I will take this into consideration!
