Just after some opinions or, even better, experience.
The web proxy server where I work currently exists within the organisations internal LAN structure (ie. traffic going to the proxy server from within the organisation does not cross the firewall). I'm wanting to move the proxy server into the security zone where the rest of our public-facing services live - notionally the DMZ. However, this will mean that all traffic from the internal networks going to the internet will cross the firewall twice in each direction, instead of once. For example:
Internal networks --> Proxy --> [ Firewall ] --> Internet
Internal networks --> [ Firewall ] --> Proxy --> [ Firewall ] --> Internet
Does anyone know if this will pose a problem for the FWSM (SW 2.3) and therefore a noticeable performance hit for the users?
Thanks in advance,
