Custom port possible with Transfer for SFTP?

We are migrating an existing on-prem SFTP server to AWS Transfer for SFTP, however the old server was setup to only accept connections on port 2222. We are hoping to make a seamless transfer to AWS behind the scenes without having users need to update anything (we use user/pass auth), but from what I can see, only port 22 is possible...

Is it possible to use a custom port or listen on multiple ports (e.g. 2222 for legacy users, 22 for go-forward users)?

Thanks,
T.

Hi,

You can set up to use a custom port by fronting a server's VPC endpoint with an NLB. Here's a post on "lift and shift" of SFTP servers that provides details on how you can set up this architecture (under "IP address portability" section step 4): https://aws.amazon.com/blogs/storage/lift-and-shift-migration-of-sftp-servers-to-aws/

Thanks,
