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

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.
