Proxy Setup Guide

Assigning a dedicated proxy to each browser profile ensures complete IP isolation between accounts. NestBrowser supports all major proxy protocols.

Supported Proxy Types

Type	Protocol	Best For
HTTP	HTTP/HTTPS	General web browsing
SOCKS5	All protocols	Recommended for most use cases
SOCKS4	TCP only	Legacy support
SSH Tunnel	SSH	Advanced, maximum security
SHADOWSOCKS	All protocols	Recommended for most use cases
VMESS	All protocols	Recommended for most use cases
VLESS	All protocols	Recommended for most use cases
TROJAN	All protocols	Recommended for most use cases

Recommendation: Use SOCKS5 for the best combination of speed, compatibility, and privacy.

Configuring a Proxy for a Profile

1. Open profile settings (click the ⚙️ icon on any profile)
2. Go to the Proxy tab
3. Select your proxy type
4. Enter the connection details:

Host:     proxy.yourprovider.com  (or IP address like 123.45.67.89)
Port:     9000
Username: your_username  (leave blank for IP-auth proxies)
Password: your_password  (leave blank for IP-auth proxies)

5. Click Test Proxy to verify the connection
6. Click Save

Reading the Proxy Test Result

After clicking Test Proxy:

✅ Success — Shows:

• External IP address
• Country and city
• ISP/Provider name

❌ Failed — Common causes:

• Wrong credentials
• Proxy server is offline or overloaded
• Firewall blocking the connection
• Wrong port number

Authentication Methods

Username + Password (Most Common)

Enter credentials directly in the proxy settings.

IP Whitelist Authentication

Some providers authenticate based on your IP address instead of a username/password:

1. Get your current IP (visit whatismyip.com)
2. Add it to the whitelist in your proxy provider’s dashboard
3. Leave username/password blank in NestBrowser

Proxy Rotation Settings

For profiles used in web scraping or bulk account creation:

• Rotate per request: New IP for every HTTP request
• Rotate per session: New IP when profile is launched
• Sticky session: Keep the same IP for the entire session (recommended for social media accounts)

Access these settings in: Profile Settings → Proxy → Advanced Options

Global Proxy Settings

Set a default proxy that applies to all new profiles:

1. Go to Settings (top-right menu) → Proxy Defaults
2. Enter your default proxy configuration
3. New profiles will inherit this proxy (can be overridden per-profile)

Checking for IP Leaks

After launching a profile with a proxy, verify there are no leaks:

1. Visit browserleaks.com/ip
   • You should see your proxy IP, not your real IP
2. Visit browserleaks.com/webrtc
   • WebRTC should show “No leak detected”
3. Visit dnsleaktest.com
   • DNS queries should resolve through your proxy, not your ISP

NestBrowser automatically blocks WebRTC leaks. If you see a leak, double-check your proxy configuration.

Proxy Provider Recommendations

For E-Commerce (Amazon, eBay, Etsy)

• Residential: Bright Data, Oxylabs, Smartproxy
• ISP Static: SOAX, NetNut

For Social Media (Facebook, TikTok, Instagram)

• Mobile: iProxy, Proxy302
• Residential: Bright Data, PacketStream

For Budget / Testing

• Datacenter: Webshare, ProxyEmpire

⚠️ Avoid free proxies — they are shared, flagged, and may log your traffic.

Troubleshooting

Proxy connects but gets slow over time: The proxy server may be overloaded. Try a different server from your provider or upgrade your proxy plan.

Account gets flagged despite using a proxy:

1. Check that you’re using a unique proxy per account (not shared between accounts)
2. Verify the proxy isn’t already flagged — try a fresh IP
3. Make sure profile timezone matches proxy location

”Connection refused” error:

• Port number may be wrong
• Your IP may not be whitelisted
• Provider may require a different connection method

Slow connection speeds: Residential proxies are inherently slower than datacenter proxies. Use geographically closer proxies to improve speed.
