I have a WRT1900ACS and trying to get OpenVPN working. I just updated to 18.06.1. With previous versions, this worked fine, but I'm following some directions from another site (as I usually do) and at the point of adding my userpass.txt field to the "auth_user_pass" field ... there is no longer an "auth_user_pass" field, nor is there a "remote" field. I've scrolled through all the "Additional Field" options of each advanced config tab, but do not see them.
