nat server configuration for CSM and ACE module

Hello,

I am in the process of migration from CSM module to ACE and I do have a question

regarding "nat server" functionality. I.e. for CSM module there is certain serverfarm

configuration:

serverfarm MID

  nat server

  nat client MID

  predictor leastconns

  real 10.36.9.135 80

   inservice

  real 10.36.9.136 80

   inservice

  real 10.36.9.137 80

   inservice

  probe MID80

  probe MIDPG

There are two NATs configured: "server nat" and "client nat" with natpool. There is no problem

with client nat configuration for ACE module. It is a quite easy to configure the same for ACE.

But - how to configure something like "nat server" on ACE module?

It seems like "nat server" is enabled by default on CSM module (that's is why it exists for every

serverfarm in CSM config).

Is it enabled by default on ACE also? Actually I did no found any mention about in manuals.

Could you help me and provide any example how to configure "nat server" or convert this part

of configuration for ACE module?

Thank you.

nat server configuration for CSM and ACE module

Hello,

I guess you have misinterpreted "nat server" on CSM.

this command only conclude that destination IP  address for the connection (i.e. VIP) has to be change when forwarding the same connection to any real server (change VIP to real server IP and real server IP back to VIP for reply connection).

this is default setting in CSM (but still visible) and default on ACE (but not visible).

there are cases where in you do not want the NAT of VIP to server IP and vice versa (IPSEC load balancing for e.g.) then in CSM you can use "no nat server" while on ACE you use "transparent"
