Proxy Chain Setup

A proxy chain routes traffic through multiple sequential proxy nodes before reaching the destination. This is useful for bypassing network segmentation or layering trust boundaries.

Option 1 — go-gost Chains (recommended)

go-gost natively supports multi-hop chains via chains in config.yaml:

services:
  - name: entry
    addr: ":8080"
    handler:
      type: http+socks5
    listener:
      type: tcp
    chain: two-hop-chain

chains:
  - name: two-hop-chain
    hops:
      - name: hop1
        nodes:
          - name: proxy1
            addr: proxy1.example.com:1080
            connector:
              type: socks5
              auth: { username: u1, password: p1 }
      - name: hop2
        nodes:
          - name: proxy2
            addr: proxy2.example.com:8080
            connector:
              type: http
              auth: { username: u2, password: p2 }

See go-gost/examples/chain-proxy.yaml.

Option 2 — proxychains-ng

# /etc/proxychains.conf
strict_chain          # enforce exact order
proxy_dns

[ProxyList]
socks5  proxy1.example.com  1080  user1  pass1
socks5  proxy2.example.com  1080  user2  pass2

proxychains curl https://example.com
proxychains nmap -sT target-host

Option 3 — SSH ProxyJump

# Jump through bastion1 to reach target
ssh -J [e-mail] [e-mail]

# Three hops
ssh -J user@hop1,user@hop2 [e-mail]

SSH config equivalent:

Host target.internal
    ProxyJump bastion1.example.com
    User deploy

Verification

# Check your exit IP through the chain
curl --proxy socks5h://localhost:8080 https://api.ipify.org
