I have a Cisco 3825 router with 2 Gig interface gig0/1 is attached with the PIX outside interfcae with the Public IP and PIX outside interface also having the public peer IP,My router E1 is connected with the ISP,Now my router gig 0/0 and Pix inside interfaces are connected to a switch.
My router is configured as the DHCP server to deliver the dynamic IP with the defauls gateway as the PIX inside interface ,and I have defined the DNS servers in the DHCP pool.Now it is working.
My actual setup is going to be like this,I will have the Proxy server,all my desktops IE will have the proxy settings,and all desk tops will have the gateway as the routers Gig 0/0 interface IP to communicate with theie local server communication.When ever the client browse it will be throgh the proxy server whose gateway is the IX inside interface IP.
We have configured the outside and inside Interface with official ipv6 adresses, set a default route on outside Interface to our router, we also have definied a rule , which also gets hits, to permit tcp from inside Interface to any6.
In Syslog I also se...
