Hi Friends,

We have a requirement we have cloud server Oracle cloud

When ever user from LAN tries to access the resources over the cloud user is able to login but unable to access any resources.

While checking in logs it is showing tcp-rst-from-client.

I am attaching the screenshot and session flow for reference.

I am also attaching the wire shark screenshot for reference.

I have tried by changing the tcp settings

Asymmetric Path to bypass.

Session Flow.

Session 125186

c2s flow:
source: 10.30.20.91 [Trust]
dst: 10.30.22.100
proto: 6
sport: 50463 dport: 443
state: INIT type: FLOW

dst user: unknown
qos node: tunnel.44, qos member N/A Qid 0

@Satyak - few points to note here

1) Assuming that your connectivity from On-Prem to Cloud is via IPSec & do you have firewall rules allowed from the firewall on cloud to the Onprem Subnets?

2)Is it only the few users or all the users facing the problem?

3) Try to induce a catch all policy to for further troubleshooting

Lets wait for more senior members to comment as well

Yes ipsec tunnel is created and rule is also created.

everyone from LAN is effected
