I am trying to run a failover setup where i have 2 isp's century link and comcast. My issue is that I have 5 static ip's with comcast but I am unable to put the comcast router into bridge mode. I have the following 70.x.x.65 -70.x.x.69 as my usable ip's and 70.x.x.70 as my gateway. I am already using most of my static ip's, .65 us my virtual ip on my firewall, .67 is assigned to the vlan on my cisco switch and 66 and 68 are assigned to my firewall interfaces. What would i assign the gigabit interface on my cisco to get this to work? I believe i only have one static ip left that I can use. Is anyone running a setup similar to this? Thanks.
