I need to do some traffic limitation/shaping to keep an old server machine online. This dinosaur is a early IBM AS400e.
Currently it is just sitting behind a fritzbox which provides port forwarding and is accessable from outside via DDNS.
The IPfire should run on a nanopi r1.
Fritz side will be red network, server side will be orange/DMZ.
Unfortunately there is some software running on that machine using a static (Lan-) IP. To make it difficult, it is hardcoded. And therefore I am forced to keep the IP’s
Fritz is at 192.168.199.1
IPfire will get 192.168.199.112
AS400e has its 192.168.199.199
Orange network: ??
Will it be possible to put the IpFire (with dedicated port forwading) direct into that Lan connection and keeping all the former assigned ip adresses?
Well, I am sorry I have not done any testing on that, as the AS400e can be a real bitch if connected to an unspecified network.
Thanks in advance
