A New Gateway

There's something fishy going on here... Someone seems to have directed us to the wrong gateway to the WAN ocean. But sometimes, even when we try the some pathway, we get access. Why is that happening? That's when we brought out our trusty (Wire)Shark to try to figure out what's going on. Who's helping us gain access?
We were given a PCAP file similar to challenge. But this time, the challenge description gave us quite a few good hints!
The hints were "directed us to the wrong gateway to the WAN ocean". So, like always, our first move would be filtering for HTTP in WireShark!
We took a look at the status code 200 OK, and we saw an interesting string U1RBTkRDT04yMDIye2NmYy15MHUyX2QzZjR1MTdfOTQ3M3c0eV83MF80X2N5ODMyX2M0MjMzMn0=
Flag: STANDCON2022{cfc-y0u2_d3f4u17_9473w4y_70_4_cy832_c42332}
We soon realised that this is a encoded string, the padding of = gave it away. We right clicked the log and followed the HTTP stream.
Afterwards, we copied the Base64 encoded string and used to decode it and we got the flag!!
