webproxy breaks commit and http access on routed client
Closed, ResolvedPublicBUG

Description

In my research for T1732, I found a some bugs with this module.

conf
set service webproxy listen-address 10.3.1.3
commit
delete service webproxy
commit
set service webproxy listen-address 10.3.1.3
commit

At this point it hangs forever. Only option is to CNTL-C. It becomes impossible to reconfigure the webproxy until you reimage the install with add system image

So you think you are safe:

CNTL-C
delete service webproxy
commit
save
`

Here's the thing. This leaves some remnant running. In a setup where the VyOS node is providing routing between a number of different vlans:

VLAN3
VLAN9
VLAN20 - HDHomeRun running here
VLAN21
VLAN22

All VLANs except VLAN22 can access port 80 on the HDHomeRun:

From VLAN22:

$ nmap -sT 10.21.21.32
Starting Nmap 7.70 ( https://nmap.org ) at 2019-10-24 17:22 CDT
Nmap scan report for 10.21.21.32
Host is up (0.0050s latency).
Not shown: 997 closed ports
PORT     STATE SERVICE
554/tcp  open  rtsp
5004/tcp open  avt-profile-1
8888/tcp open  sun-answerbook

From any other VLAN:

$ nmap -sT 10.21.21.32
Starting Nmap 7.70 ( https://nmap.org ) at 2019-10-24 17:23 CDT
Nmap scan report for 10.21.21.32
Host is up (0.0049s latency).
Not shown: 996 closed ports
PORT     STATE SERVICE
80/tcp   open  http
554/tcp  open  rtsp
5004/tcp open  avt-profile-1
8888/tcp open  sun-answerbook

The fix to that problem is a reboot.

@kroy Can you re-check it with your environment? I can't reproduce it in 1.3.0-rc5.
