I have a static IP address from my ISP. I also have a router with a built in Modem so I plug the router into the telephone line. If I make a direct connection from my router to my PC with the following addresses on my PC everything works fine, I get a connection to the internet (can view webpages):
IP: 184.108.40.206 Subnet: 255.255.255.250 Default Gateway: 220.127.116.11
Preferred DNS : 18.104.22.168 Alternate DNS : 22.214.171.124
As soon as I connect my Cisco 501 PIX in between the PC and the router, I don't get any internet connection. Here are the steps I am following to configure the firewall, so please guide me where I am going wrong:
I start the PDM by going to https://192.168.1.1/startup.html Once started and authenticated get the Basic Configuration and I leave the default values ( PIX Host Name = pixfirewall, Domain Name: ciscopix.com)
On the next page "Outside Interface Configuration" I leave the "Speed to Auto" and I select "static IP address" and input the following details IP 126.96.36.199, Subnet Mask: 255.255.255.250 and Default Gateway: 188.8.131.52
On the next page I leave the remote VPN page empty
On the next page I also leave the Auto update Configuration empty
On the next page "Other Interfaces Configuration I can see the Inside and outside interface settings and the inside has a security level of100 and the outside has 0.
On the next page "NAT and PAT Configuration" I select "do not translate any addresses.
On the next page I disable the DHCP because I can allocate a specific IP for the PC connecting to the Firewall.
After applying all these setting and saving them. I specify TCP/IP for my PC with the following addresses:
IP: 192.168.1.10 Subnet Mask: 255.255.255.0 Default Gateway : 192.168.1.1
I try to connect to the internet but I will not let me connect. For some reason Skype is able to connect which is quite strange.
Do I need to configure anything more? Why does it not allow me to connect to the internet?
When I remove the firewall I am getting a connection. Please can you guide me?
Thank you, James
