I have a network setup which looks like the
above.
I am doing VLANs using a Layer-2 switch, so as per
the above diagram, in VLAN-1 I have the inside interface of the firewall and the
outside interface of the Local Director and in VLAN-2 I have the inside
interface of the Local Director and 5 hosts, 3 web servers (mysitename.com,
which are to be load balanced), 1 mail server (mail.mysitename.com, to which
external mail servers would connect to send mail) and 1 chat server
(chat.mysitename.com, to which browsing clients would connect to
chat).
What I would like to know is how would I do the
routing of the packets and the IP addressing.
Is there a possiblity of defining multiple IP
addresses on the outside interface of the firewall, in which case I would NAT my
virtual IP address for the web servers (that is defined on the Local Director)
to 1 public IP address on the outside interface, another virtual IP on the Local
Director for the chat server to another public IP address on the outside
interface of the firewall and so on.
Note: I am not averse to moving the chat server and
the mail server to VLAN-1, but my problem would still remain the
same.
Thanks for your help
