we are using F5 to Deliver SMS messages using SMPP to third party provider through VPN connection,
the problem is the provider is accepting 2 connection sessions per time, while our servers are initiating more than 2 sessions ...
can i tweak in TCP profile at F5 to help to manage and solve this issue ?
Thanx

You can set a connection limit on the node or pool member to limit the number of TCP connections LTM opens to them. You might also try enabling OneConnect to re-use the serverside TCP connections. Though I'm not sure whether SMPP would work well with multiple client sessions using the same TCP connection.

tried both and didnt work..
is there anyway to queue the sessions then start purging them according to the open session to the server?

There isn't a practical way to queue connections to an LTM VIP that I know of.
When you say the two options didn't work, what were the symptoms? Did LTM open more connections than the connection limit for the node? Or did the client not handle the response from the VIP?
With OneConnect enabled, you should see LTM re-use the serverside connections for multiple clientside connections. With this profile added to the VIP, what did you see happening?
