The demand for several internal systems within the company to connect to WireGuard for access has led to the replacement of a Chinese-made web VPN. Despite the switch, the WireGuard client on iOS and most VPN software tends to redirect all app traffic, which causes issues with the company's 30Mbps speed limit. Furthermore, the auditing process requires constant switching between different public and private IP addresses, making it difficult to configure traffic rules. To address this issue, I aim to develop a browser extension that can automatically configure routing and divide traffic for company intranet access once the domain name is parsed. However, testing has shown that this approach is not effective, as many company services use public SaaS providers such as Dingding, which results in IP address conflicts.
