Job Description – Need Network Technician for VPN Routing Issue (WireGuard + GlobalProtect + SAP) I am using a router configured with WireGuard, which sets my public IP location to Milan. This part works correctly. I work for Accenture, and I also need to connect to my company VPN (GlobalProtect) to access SAP. Here is the issue: • When I connect to my router, my IP shows Milan as expected. • I can successfully connect to GlobalProtect while WireGuard is active. • But when I try to log into SAP, the connection never completes — it keeps loading without showing any error. • If I disable WireGuard, SAP works normally. • I need SAP to work while both WireGuard (on the router) and GlobalProtect (work VPN) are active at the same time. Goal I need a t...

Please work only under my explicit authorization and within all legal boundaries. Deliverables • A clear, step-by-step report explaining findings for both devices &bu...

I manage an Instagram group that has been hit with repeated malicious posts. My goal is to discover exactly who is behind them so I can protect the community and take the right action. Here is what I already have on hand: • Usernames involved in the attacks • Several matching IP addresses • Names and contact details tied to some of those accounts I have not seen any clear timing pattern—the posts appear random—so I’m hoping your investigative skills can fill in the gaps. What I need from you: 1. Analyse the data I provide and trace each malicious account back to the real individual operating it. 2. Document your findings in a concise report that shows how you linked each username or IP to a confirmed identity (screenshots, lookup logs, or o...
