# Outbound firewall (anti-cheat): allow ONLY DNS, loopback, docker-internal networks, and the LLM API
# endpoints the agent needs. Everything else is dropped — in particular pypi, github, and huggingface,
# so the agent cannot `pip install vllm` / `pip install sglang` / clone the reference moe_align kernel and
# copy it. torch + triton are already in the image, and mini-swe-agent is pre-installed (harbor's patched
# installer skips the network install when it is already present), so no package index is needed at run time.
#
# Runs as the container ENTRYPOINT before the CMD. iptables rules are network-namespace-wide, so they also
# apply to the agent's `docker exec` commands. Requires cap_add: NET_ADMIN.

# LLM API endpoints the agent may reach. Extend at launch via ALLOWED_HOSTS=host1,host2 (no scheme).
