Just a remark: Could you be a bit more precise about your setup.

If datacenter 1 is some product, please post the vendor / producer.

How are they connected, is there a firewall and such.

Thank you,
Tolomir

Alright, did some masking to ensure your privacy.

I guess these datacenters are across a country / different countries and there is a firewall at each borderline?

Well here is the manual:

Could you describe what you want to do:  port 25 is smtp - outgoing mail traffic, should you send emails to these data centers, or should they be allowed to send email to you?

Is that vigor @ home or in a branch office?

I'm asking because outgoing email traffic should not be blocked by the vigor (had a 2500WE myself)
But incoming traffic is discaded by default. At least if you didn't initialize the communication. (-> tcp handshake)
