RE: Dynamics GP Web Client Error
Because the certificate is only for *inside* the network and probably uses the machine name where it was created. If the URL to access the server is different on the outside then your certificate will not work, hence the certificate error. Self-signed certificates are not recommended for full blown intra/extra net implementations of web client. You are better off with an Active Directory Certificate Store certificate or a certificate issued by a Third-party Certification Authority such as Comodo, Symantec, GoDaddy, GlobalSign, DigiCert, Verizon or the likes. A Third-party Certification Authority will only issue a certificate for the public facing URL, i.e., somecompany.com, so you will need to setup your routing tables to map internal server names to, let's say, gp.somecompany.com
