Details

pumaglued is the ATOM to ARM Inter-CPU connector for Puma6 / Puma7 cable models.
It is started on the ARM CPU by E41-pumaglued or vendor.pcd and serves various purposes:

TCP proxy:

pumaglued is a tcp proxy serving the ATOM Webinterface to 192.168.100.1 on ARM - fw 7.29 armconsole: 

# netstat -luntp | grep pumaglued

tcp        0      0 192.168.100.1:80        0.0.0.0:*               LISTEN      678/pumaglued

proxy 192.168.100.1:443 -> 169.254.1.1:443

192.168.100.1 is the hardcoded IP of the ARM interface lan0, 169.254.1.1 is the acc0 interface IP of the ATOM. 

# ifconfig lan0

192.168.100.1 / lan0 seems to be for the ISP since it also serves SNMP: 

# netstat -luntp | grep 192.168.100.1

Unfortunately there is no pumacmfltstats QUERY to get a list of possible stats types.

HTTP webserver:

Besides the proxied main Webinterface pumaglued runs an own HTTP only webserver, listening on all ipv4/ipv6 addresses.
This explains why it requires libwebsrv.so.

fw 7.29 armconsole: 

# aicmd pumaglued avmcsock show csock | grep http

9   ; [::]:3128 'http server'                 ;     listen                                  ; inet6,stream                  ;

# wget http://localhost:3128/

Connecting to localhost:3128 (127.0.0.1:3128)
wget: server returned error: HTTP/1.1 404 Not Found

Ok, it works but we need a valid URL. 

# ls -lR  /usr/www

/usr/www:
drwxr-xr-x    2 root     root            36 Nov  5  2021 cgi-bin

/usr/www/cgi-bin:
lrwxrwxrwx    1 root     root            22 Nov  5  2021 system_status -> /usr/bin/system_status

# ls -l /usr/bin/system_status

-rwxr-xr-x    1 root     root          1141 Nov  5  2021 /usr/bin/system_status

Ok, we have just one file in webspace, let's try it: 

# wget http://localhost:3128/cgi-bin/system_status

Connecting to localhost:3128 (127.0.0.1:3128)
wget: server returned error: HTTP/1.1 404 Not Found

Hmmm, strange.

Port forwarding:

pumaglued can enable SNMP and TR-069 ports on the wan0 interface.
This is controlled by the avmipc states snmp_allowed and tr069_allowed.
Both states are sent by dsld on the ATOM CPU, depending on 2 settings in ar7.cfg: 

unattended_update {
       ...
       enable_snmp_on_wan = yes;
       enable_tr069_on_wan = no;
       ...
}

Both are used to call the resspective functions of libpumacmflt.so, which controls pumacmflt.ko
to forward the respective ports from the wan0 interface to the internal lan0 modem interface.

For TR-069 the TCP proxy additionally adds a proxy rule to forward the TR-069 port to the ATOM CPU.
