Google captcha

I run a small ISP, clients are behind a NAT. They are split to use two public ips.
example 200 on one ip and 200 on the other. They all get the captcha request when doing a google search.
How do i resolve this issue. Many thanks.

Nope. I haven’t.

You’ll need more public ips to spread the nat between them, or google (and other services) will detect an excessive connection count from the same IP.
