Hi @naveen.palani ,
As far as I know, you can add folders or services to allow list while the port Access Mode is set to deny by default. Regular expression support is limited, I do not think you can exclude specific services /folders here.
However you can add multiple services at the same time by using the option on the right side of the page and select an ACL which would list all services and then you can choose.
As the admin guide mentions, Reverb
a. In the Select an ACL list, select the ACL used as the execute ACL for the elements for which you want to allow access.
Integration Server Administrator displays and selects all of the elements that use the selected ACL as the execute ACL.
b. To add all of the selected items to the allow list on the left side of the page, click Append Selected.
Integration Server appends the selected entries to the existing list.
c. If you do not want to add all of the items to the allow list, deselect the ones you do not want. To deselect multiple items, press the CTRL key while deselecting. To add the remaining items to the list of allowed services for the port, click Append Selected.
Integration Server appends the selected entries to the existing list.
Hope that helps,
NP
