Cannot use SSH via internal IP address but can ping it easily

I have this setup in Oracle Cloud Infrastructure ... I have two networks .. **Network 1**: internal cidr: 192.168.1.0/24 public IP: 10.0.0.1 **Network 2**: internal cidr: 192.168.2.0/24 public IP: 10.0.0.2 connected via OCI tool -> "Local Peering Gateway" (without this, I couldn't even ping) ... both are running SSHD and are accessible/connectable via SSH by their PUBLIC IP addresses .. This all works fine ... However, when I want to connect from the Network 1 to Network two via internal IP address, I cannot ... even tho it pings fine admin@network1:$ ping 192.168.2.10 PING 192.168.2.10 (192.168.2.10) 56(84) bytes of data. 64 bytes from 192.168.2.10: icmp_seq=1 ttl=54 time=154 ms 64 bytes from 192.168.2.10: icmp_seq=2 ttl=54 time=152 ms from tho other network, I cannot ping tho admin@network2:$ ping 192.168.1.10 PING 192.168.1.10 (192.168.1.10) 56(84) bytes of data. --- 155.0.10.38 ping statistics --- 347 packets transmitted, 0 received, 100% packet loss, time 354309ms The traceroute shows a lot of asterisks on the way .. and nmap from both machines does not show any open ports ... which is weird because publicly they are opened and I cannot via the public IP using ssh without a problem... Any idea what could it be? I am kinda helpless .... especially because of OCI does not really provide support on this matter and many services do not provide logs :( PS: Pls do not advice to change the provider/cloud .. I cannot - that's clients request .. ----------- EDIT: wireshark ping log admin@network1$ sudo tshark -i ens3 | grep 192.168.2.10 Running as user "root" and group "root". This could be dangerous.
