Access SAP Server remotely using SAP GUI

[former_member355261]

Hello,

I made two different SAP ECC6 EHP6 IDES installations in two systems of my personal LAN at home using WIFI.

I then used dynDNS to point out on my public IP address.

I also opened the necessary ports for the two PCs (192.168.1.5 and 192.168.1.6) on the router.

Now the problem is in SAP GUI, I can access only to one of the two systems remotely even if fill the System ID field with the other value, I'm always connected to the same system and I don't know why.

Please help me find a solution to this problem.

Thanks in advance.

you need 2 different IP address on the Internet...

or, you configure your router to listen to different ports.

do you mean that with one public IP address I only can access one SAP system even if I have many in my LAN ?

[former_member204746 · Accepted solution]

by default, yes... but, there are ways to change this...

You will need a router that will use NAT and change incoming/outgoing ports.

a network specialist can help you this... or, go on the website of your router and see if such option exists.

Actually, I found a solution for my problem. It's to change the instance number of one of the systems (01 instead of 00) and automatically the ports change too ( 3201 instead of 3200, ...)

I'm surprised that this is enough.

changing port number is part of the answer, but you only have 1 Internet address. How will you map this to 2 different IP internal adresses?

you will need to tweak your router/firewall...

hi occoro,

may be in hosts file one ip is mapped due to which  it is always connecting to one server.

in the sap gui are you mentioning the ip or hostname?

[former_member355261]

Hi,

In the SAP GUI I'm mentioning the hostname, and even if I mention the IP I get the same result !

is the hostname same for both SAP systems?

[former_member355261]

No they have different hostnames, but I'm using the hostname provided by dynDNS which points on my public IP address dynamically.
