# Egress IP addresses

> Static outbound IP addresses used by the Synthflow platform, organized by region. Allow-list these in your firewall when Synthflow needs to reach your infrastructure.

When Synthflow connects to your infrastructure (webhooks, custom actions, MCP servers, or any other outbound HTTP request), traffic originates from a fixed set of IP addresses. If your network requires an allow-list for inbound connections, add the addresses below for your region.

<Info>
  Synthflow operates three regions: **Global**, **US**, and **EU**. Only allow-list the addresses for the region your workspace is in. You can find your region under **Settings > Preferences > Customer Region** in the Synthflow portal.
</Info>

<Warning>
  These addresses cover **platform-level** outbound traffic (API callbacks, webhooks, MCP, custom actions). For SIP signalling and RTP media addresses, see [SIP Trunking Network ACL](/sip-trunking-acl).
