Its not an answer for your question rather a question again.
My Requirements,
1. Primary and standby, all traffic goes to primary.
2. When primary fails, I want my existing connections also switch to standby.
2. When primary fails then later comes back, I want my traffic (new and existing) go back to primary.
3. When the both nodes are down, I want all the existing and new connections should drop.
Your configuration is almost matching for my requirement, could you share, which configuration should I have.
Thanks in advance.
