Hi Everyone,
I followed the Web Proxy Instructions to the dot which is below.

/ip firewall nat
add action=redirect chain=dstnat dst-port=80 protocol=tcp to-ports=8080

/ip firewall filter
add action=drop chain=input dst-port=8080 protocol=tcp

/ip proxy
set always-from-cache=no cache-administrator=servicedesk@company.com cache-hit-dscp=4 cache-on-disk=no enabled=yes max-cache-size=unlimited max-client-connections=600 max-fresh-time=3d max-server-connections=\
600 parent-proxy=0.0.0.0 parent-proxy-port=0 port=8080 serialize-connections=no src-address=0.0.0.0

add action=deny disabled=no dst-host=*.sample.com



Once this happens my users will see this message when they search google


We're sorry...

... but your computer or network may be sending automated queries. To protect our users, we can't process your request right now.

Based on google:
1. There is an unusual traffic from your computer network
2. Check for malware on your computer.

But when I disable both the filter and nat rule for my web proxy google works again. The problem is my users can access all the websites again.

Please help me.

Jess

This also happens even when I remove the web proxy. Has anyone encountered this before?

Has anyone experienced receiving captcha's when accessing google in Mikrotik?

Nope. I haven't.

I had similar problems due to improper web-proxy configuration.
I created firewall rules and all "external" proxy attempts were then logged to an address list, then dropped.
Interestingly, all proxy/IP "theft" was coming from Poland. Supposedly, the 3rd largest source of spam on the web!
This ultimately cleared the Google captcha, after "blocking" these IP's.
I thought the source of the problem was internal. As google and others imply, though found the source to be definitely external!
I also changed my public IP, as boen_robot mentioned.

Wanted to add:
This was all discovered and couldn't have been resolved without the gracious help from Richard, aka. CelticComms!
If you need an excellent consultant. He's the man.
Thanks again Richard!

yes i toooo,

but
i disable web-proxy and also webproxy transport rule from Nat...
