I've a dialup connection 9600b/s of speed with a remote web server host 192.168.254.2 , my local clients are able to connect to that with nat trought 192.168.1.1 that is the router

192.168.1.10 lan client > connect to router 192.168.1.1:88 that nat to remote host 192.168.254.2:80

if web proxy is enabled it run on 8080, if I add another nat from 88 to 8080 the rule take precedence and cannot access 192.168.254.2:80 how can I cache the data from 192.168.254.2?

Thanks, BR

For routeros internal proxy you need action=redirect to 8080, not dst-nat.

Thank you with redirect I get the proxy web page, but it says Connection Refused.

I've tried to add 192.168.254.2:80 in web proxy access rules but it seems ignored, it only seems to work with method:DENY and REDIRECT-TO but it won't load the page.

How can client connect from lan x.x.1.x to remote host x.x.254.x?

it says Connection Refused.

Looks like web server won't accept that connection. Check out his logs. May be there is some restrictions in server settings
