Replacing page content on gateway (FreeBSD)?

Question

FreeBSD

Hello! There is a gateway on FreeBSD 9.2, ipfw nat. There are several sites that require you to replace one piece of HTML with another when accessing it. Support for regular expressions is desirable, because replacement pieces may vary slightly. What can you recommend? I would be grateful for any suggestions and suggestions.

Answer 1

Squid as transparent proxy + redirector on it. For example, our redirector randomly rotated pictures of some social networks.

Answer 2

As an option, you can use suricata , there is an article on Habré that gives some description.

Answer 3

squid+rejik or squidguard or dansguardian I
use the latter in production, it's very convenient.
