Here is my situation, I have a Cisco 2600 with a modem bank and VPN access. I also have a proxy server which only allows internet access to a certain range of IP addresses. Between internet, non-internet, and static addresses my internal network ip address scheme needs to be expanded as I am quickly running out of IP addresses on the 10.10.1.X network. I want to expand this network so that i can put my internet addresses on something like the 10.10.10.X network. for this reason i have been considering resubnetting traffic on my Fe0/0 interface to add a greater range. The issue that I am worried about is that as you can see from my interface attachment, we use 10.10.2.X for the DMZ, 10.10.3.x for the Async bank and 10.10.4.x for the VPN addressing all on different interfaces. In addition we have hardware to hardware VPNs established in the 10.10.6.x and the 10.10.50.x areas.
ideally I would like fe0/0 to handle something like 10.10.1.x, 10.10.5.x and 10.10.10.x addresses but not necessarily the other ranges on the VPN and alternate interfaces. If I change my subnet mask on fe0/0 to a 255.255.0.0 will that interfere with traffic on the other interfaces? Is there a better way to do this without resubnetting or am i correct and our growth has made this necessary.
Any assistance you can give on this would be much appreciated
