Maybe they're assuming that port 443 means you have a certificate installed on your web server?
As in, they wouldn't provide one to you if they're connecting to your server. If so, just slap a publicly issued cert on your web service, and presuming their client understands TLS (and it should, since it's consuming a web service), instant encryption.

So I ask them if we couldn't just create a vpn tunnel from their server through my firewall to the webservice running internally. They reply no just open your firewall and whitelist our address then nat the traffic to the webservice. I am a little more than wondering how they get away with this format for shipping data to financial institutions? -----Original Message----- From: [email protected]<mailto:[email protected]> [mailto:[email protected]<mailto:[email protected]>] On Behalf Of Kurt Buff Sent: Thursday, December 18, 2014 3:32 PM To: [email protected]<mailto:[email protected]> Subject: Re: [NTSysADM] Weird request from a vendor On Thu, Dec 18, 2014 at 12:26 PM, David McSpadden <[email protected]<mailto:[email protected]>> wrote: > You ever heard of someone whitelisting a server on the Internet to > push data through a firewall on port 443? More details needed, but yes, I've put up firewall rules for specific ports and addresses. Very common. Kurt
