You can allow egress to a subset of your IP address space from your on-prem data center to the Internet with Aviatrix Egress FireNet. Static CIDR egress is supported on Aviatrix Transit and AWS Transit Gateways (TGW). Up to 20 subnets are supported.

Enter the static CIDRs in the field and click Change. This changes the egress static CIDR attribute for the selected FireNet to the value you entered.
