Hello,
I'm engaged in a project where we need to NAT an unusually large number of IP addresses out of AWS (~300). Our current datacenter solution is Cisco ASA and we'd like to use ASAv in AWS to maintain consistency.
Unfortunately, AWS restricts the number of IP addresses per interface:
https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/using-eni.html
With the largest instance size available (c5.4xlarge) I've been able to validate that I can have 8 interfaces and "max" out at 210 IPs (by having one inside interface and 7 outside interfaces).
Are there any plans to support larger instances sizes (specifically c5.18xlarge) with ASAv?
If not, are there any suggestions for alternatives? I attempted using a CSR but its largest available size is c5.9xlarge.
Also, as a current Cisco customer, do I have any avenues to discuss our challenge? i.e. a way to engage the product team?
I did try launching the ASAv marketplace image and increasing its size but it is restricted by the marketplace definition:
Thanks for any assistance!
