Title: how firewall section and proxy section affect on each other Post by: kikilinux on Tuesday 15 October 2013, 03:04:07 am Hi
Maybe i have a miss understanding from firewall functionality with proxy I want to enable proxy and for example block http traffic from green zone to DMZ zone, can i perform this ? Do i say right, when i use proxy then i can't filter traffic by firewall ? best Title: Re: how firewall section and proxy section affect on each other Post by: kikilinux on Tuesday 29 October 2013, 05:23:49 am nobody can answer my question ???
can we use http proxy and firewall together ? when we use transparent http proxy then we can't use firewall in inter-zone or outgoing state ? anybody knows ? best Title: Re: how firewall section and proxy section affect on each other Post by: jfinnigan on Tuesday 29 October 2013, 09:39:28 am Yes, you can. I think you are missunderstanding the purpose of a proxy/content filter and a firewall. They work at different layers in the OSI model. A firewall works at layer3 and stops or allows traffic bases on ACLs and their associated ip addresses and port numbers. It doesn't care or know what's inside those packets. A firewall would be what you use to stop or allow access to a particular network. The proxy content filter is what you'd use to block users from access certain internet websites.
Hope that helps. |
