Hi,
I'm not sure if it's the right place for my question!?
We are running an ASL to secure a DMZ and an internal LAN. Within the DMZ we normally have three web-/ mailservers running. Because of trouble with our leased line provider we had to colocate those servers to another ISP. At the ISPs place we have IP number say 1.2.3.4 for one of the servers.
This server server should now be taken back to our DMZ to be accessed by IP number 5.6.7.8 AND by IP number 1.2.3.4 as long as the nameserver entries are mixed up between 1.2.3.4 and 5.6.7.8 for the same server (it will take about 1-7 days for a DNS change ...).
I know how to setup natting to provide DMZ ip number 192.168.100.8 for IP number 5.6.7.8 .
My question is: How can I route also IP number 1.2.3.4 to IP number 5.6.7.8 (or to 192.168.100.8)? Do I have to setup another ASL at the ISPs colocation place? Or is a normal Linux box suitable?
Hopefully I explained my question the right way... B-)
Best regards,
Jens Hauser
