I would like help with packages between sophos xg and an oracle application

Hi guys.

I'm sorry for my bad English
People I have a problem that I can't solve.
I have an XG that makes a connection IPSEC VPN site-to-site through which the requests of a local application that queries an oracle bank travels, these queries are being forcibly closed as shown in the image below.

these queries are made directly on a specific ip on port 1521, if we try 2 or 3 times it works, already checked via tcp dump the connections for this ip and this port as shown in the image below and I can't identify the problem could they help me?

My local network is 10.10.30.0/24 and the db machine is on the remote ip 10.10.10.7

my Ipsec config.

Hi DbSs TI

Thanks for sharing detail information with snapshot. Is site to site IPSec tunnel between XG to XG or XG to another vendor?

Are you getting any drop packet on XG on remote server IP during error on Application?

You may collect TCPDUMP, PCAP and Drop packet on remote Oracale IP on XG and note down the time details for error and during issue timestamp you may check PCAP details to have further verification.

PCAP KBA:

For testing purpose if you access same App over WAN ( by publishing through DNAT) are you getting the same problem or error?

Hello, I did the capture and analysis I didn't see any drop, some connection alerts but nothing that aborts the connection, below is an image of the conversation between the hosts.
