what does that mean output of VPN tu shows as (i=0)
INBOUND: 1. xxxxxxxx (i: 0) OUTBOUND: 1. xxxxxxxxx (i: 0)
For each IPSec tunnel, there are two Security Associations (SAs) formed: inbound and outbound. Although we tend to refer to this VPN Tunnel in the singular, it actually consists of two "flows" of encrypted data: inbound and outbound. A similar concept is employed in the state table element "connections" where each connection is tracked as two separate flows referred to as c2s (client to server - outbound) and s2c (server to client - inbound).

thanks. what does it mean by i:0
I believe on an R80.10+ gateway the i:0 indicates the CoreXL Firewall Worker Instance number (in this case instance #0) that is handling that SA.
it is a standalone firewall, I see for other tunnels different numbers . I would say 1-9
