i intend to purchase a cisco ehwic 3g hspa +7 interface card for back up internet connection. This card does not have a lan port. The 3G provider has agreed to assign a public ip to this sim. How do i make a host sitting behind the router to get a public ip address from this 3G sim.
I have read some article where some routers such as draytex 2862ln router using a routing subnet feature. I want to know if cisco 2911 router has some features that can support that
The 3G sim isp has assigned only one public ip address to the sim. There is no extra public ip. However,the isp said if i needed more than one ip address,i should order two sims.
I was thinking that the ip address for NAT should be exlcuded from the nat pool.There is no nat pool in this case.i dont know if the following will work
1. Ip nat inside source list private-lan interface cellular 0
2. ip nat inside source static 192.168.1.1 184.108.40.206
220.127.116.11 is the sim ip which is the interface cellular 0.wont there be any issue since i am using the same 18.104.22.168 for nat 1:1
Hello Francesco,My goal is this: i have cisco expressway c and e deployed that allow Mobile and remote access users to communicate with the lan users. The expressway edge has two lan interfaces. Lan1 has a private ip address while lan 2 is to have a public ip or to use a private ip which is mapped to a public ip using static nat. There is an option for you to enable static nat and enter the public ip.
I am kind of confused since the 3G sim has only one public ip address. If i put the 3G sim public ip,i dont know if it is going to work since 3G sim will be inserted in a cisco 3G EHWIC card
