more than one ofbiz e-commerce running

[SPEELGOED VOOR KINDEREN / TOYS FOR CHILDREN / JOUETS POUR ENFANTS]

Hello,

Is it possible to run two e-shops on the same ip-address but with two
different access ports, for example
one e-shop website on port 80 with own product store x
and
other e-shop website on port 81 with own product store y

and running only one instance from the ofbiz software?

regards,
Heidi
