Whitelisting of Marketo IP's

[Anonymous]

I've been setting up a webhook from Marketo to our company and everything worked fine from sandbox when I enabled the access from Marketo IP as is written on Whitelist Page

But from production environment it allways fails with message "couldn't connect to host".

I logged the traffic and discovered that there is IP address range missing in that article 98.129.93.0 / 24 ? or something of that kind.

Nothing happened after adding a comment into article, so I try this discussion.

Yes that's true, it is primarily for emails, new article will be fine, but most probably there will be the same IP ranges....

The whitelist is primarily intended for emails. It makes sense to consider a separate article for webhooks though.

Hello again,
Thank you for quick answer, but the IP 98.129.93.0 / 24  means IP range from IP addresses 98.129.93.0 to  98.129.93.255.
After adding of this filter the webhook is passing through firewall fine, but the article that I mentioned does not contain this IP address range, so I was unable to filter it properly for first time.

I'd like to suggest to update that whitelist  table with all IP addresses from which may the emails/ webhooks  come.

It may be set by a corporate firewall. However I believe that IP may be not accurate:

brenogomes$ ping 98.129.93.0

Please engage your IT to review the frewall policies, keeping in mind the IP must be valid.
