Hello
When a customer communicates with Cisco WebX, the service is not available.
I used tcpdump on the external interface of the firewall and found something unusual.
I will divide the situation into two types: normal and unnormal.
1. Unnromal situation
- When viewing pcap information in wireshark, the src of payload is displayed as private IP.
- I know the NAT IP information should be visible. Is that correct?
2. Normal situation
- When viewing pcap information in wireshark, the src of payload is displayed as NAT IP.
- Communication goes well without any problems.
Is it correct to see this as abnormal processing when processing traffic at the checkpoint? Or is there anything else I am missing?
