Formstack is improving the stability of outgoing integrations by adding IP Addresses. Action may be required.
If you have added Formstack’s IP to your firewall or other security mechanism, you will need to add additional IPs to your allow-list any time BEFORE September 24, 2021. Below is the complete list.
- 188.8.131.52 (existing IP)
- 184.108.40.206 (new)
- 220.127.116.11 (new)
- 18.104.22.168 (new)
- 22.214.171.124 (new)
- 126.96.36.199 (new)
If your system requires an allow-list and you have not added these new IPs by September 24, you may start seeing integrations (such as Webhooks, SMTP, and LDAP) randomly fail. Please contact support if you need further assistance.
