Hi, We have cisco 1841 router with 2 FE ports, IOS version running on the router is 12.4(3d). I have connected 1 ethernet to internet and other to internal network. To get connected to internet I have created ip nat inside source list <NUMBER> interface fa0/1 overload. I have also added ip nat inside on internal FE and ip nat outside on External FE. I have also added default rotuer 0.0.0.0 0.0.0.0 <next hop>.
I also have a web server on my network so i have created static nat. ip nat inside source static <local Network> <IP Suppliled By ISP>.
This work fine but suddenly users from outside will not be able to reach this server, when i try to ping internet from the server during this period I will not be able to reach but i will be able to do so from the router. To reinitiate connection I will have to reset the Network card on the server.
I only have problem when there is traffice to server.
Hi I have made the changes as suggested lets observe. The other Q is I only need http, https, RDP (Terminal Service), and ICMP to be allowed to this Server so that we can block malicious activity and attacks.
If you notice I have blocked ports used by nachi and blaster worm.
Can you let me know what accesslist should i have?.
