We don't have enough public IP's but we want to have several real |
| 2 |
servers for different customers (SSH, Mail, etc.) in the private subnet. |
| 3 |
|
| 4 |
I also plan to switch from Microsoft ISA Server to an |
| 5 |
Open-Source-Solution with Linux. The solution can be simply done for |
| 6 |
webservers, but we need a solution for several services. |
| 7 |
|
| 8 |
I try to figure out the problem with a simple example: |
| 9 |
host1.domain.net IN A 1.2.3.4 |
| 10 |
host2.domain.net IN A 1.2.3.4 |
| 11 |
The gateway (1.2.3.4) should dynamicaly open a tunnel to |
| 12 |
192.168.0.1 if the query is for host1.domain.net |
| 13 |
and to |
| 14 |
192.168.0.2 if the query is for host2.domain.net |
| 15 |
|
| 16 |
If you need more details feel free to ask. |
