Accessing internet from a NLB

Hi..

I have 2 servers running a NLB, they have internal
adresses 192.168.100.1 and 192.168.100.2

The cluster has the external ip-adress 193.13.xxx.xxx.

When your accessing internet from the primary server in
the cluster everything is fine, but it's impossible to
access from the second server. Is it suppose to be that
way or have we configured it all wrong?

Thanks,
Alex

Hi Alex
NLB does not restrict or prevent outgoing connections from any node in the cluster. However, if the outgoing connection request (TCP SYN packet) had the cluster IP address as its source IP, then, you would have a problem: the reply (TCP SYN+ACK packet) would be addressed to the cluster IP address and hence, will be load balanced by NLB and could end up in a node that did NOT initiate the connection. So, please make sure that connections are not initiated with the cluster IP address.
