firewall: transparent proxy rule leaks into rules page

[oparoz]

Env

15.7.99_2050

Steps to reproduce

1. Go to Services -> Proxy Server
2. Click on the Forward Proxy tab
3. Click on advanced mode
4. Click on the (i) for Enable Transparent HTTP proxy
5. Click on add a new firewall rule
6. Pick an interface and save the rule
7. Go to Firewall: Rules
8. Click on the tab matching the interface chosen above
9. Edit the rule called NAT redirect traffic to proxy
10. Change the gateway (it's not greyed out)
11. Save

Expected result

I should be able to save the rule

Actual result

The Javascript validation rules get in the way, thinking that all greyed out fields are fields which have not been filled.

Can you please refine the terminology and exact page names for steps 1., 2. and 3., I am unable to reproduce this with the current description.

[oparoz]

OK, I've updated the OP.

Is this the error you're seeing?

The following input errors were detected:
The field Protocol is required.
The field Source is required.
The field Destination is required.
The field Source bit count is required.
The field Destination bit count is required.
is not a valid source IP address or alias.
A valid source bit count must be specified.
is not a valid destination IP address or alias.
A valid destination bit count must be specified.

Exactly and all of these fields are filled up, but greyed out to prevent bad things to happen.

Ok, it's a NAT rule and it shouldn't show up in the rules screen.

[oparoz]

OK, so it's the same rule as the Port Forward rule, but presented differently?

[fichtner]

exactly, and since it's a NAT rule it fails to save properly in the rules screen

OK, thanks 👍
