Nimbostratushow to configure inbound NAT?
Hello,
I would like to achieve the following:
do SSH on port 22 from an external host towards the Virtual Server IP of the F5.
F5 should translate the Virtual Server IP to an internal.
For examp...

NimbostratusHello Nathan,
As a test I configured as you suggest a VS (port 22) with only one member in the pool. SSH works then fine.
What I ultimately would like to achieve is the following: ssh "VS-IP" -p 2201 -> ssh internal-node-1 ssh "VS-IP" -p 2202 -> ssh internal-node-2 ssh "VS-IP" -p 2203 -> ssh internal-node-3 ssh "VS-IP" -p 2204 -> ssh internal-node-4
So I need a mechanism to translate the port from 220x to 22 In the VS-config I see a field "port translation" (enabled by default). I can't find a clear description in the F5 docs what this parameter is actually doing.
Regards, Marcel

Port Translation means destination port translation, i.e. the VS could listen on port 2201 and the pool member has port 22 associated with it, this setting enabled means the port is indeed translated from 2201 to 22. Where you might have that disabled if you have a wildcard port VS and wildcard port on the pool member. Hope that clears that up for you.- m_radstake_1687Now I understand the principle. It works. Thanks again!
- natheNo probs. Glad I could help.
