Sorry for opening a new thread, but I need some information on howto establish a firewall rule. I already playing around for some days and also read through documentation and I still need help to understand what I have to do to allow teamviewer connections.
It would already help to know, if the rule has to be placed in rules, or local rules. And having ndpi installed if the ndpi service teamviewer has to be used, and/or if a service - lets call it teamviewer_port for port 5938 has to be created and used in the corresponding rule or local rule to be created. Or do I have to create a network service under system / settings instead in Firewall / Objects / Services?
And does it have to be a rule from red to red as Log showing IN=eth1 OUT=eth1 which for me does not make sense, or would it be green or local lan as source and red for destination??
The strange thing is that on different tries sometimes connection can be established, but soon after on a next try, there are blocked connections again in error log.
Folowing an example line of the connections, I try to allow, but that are still blocked by firewall:
Jul 14 15:52:17 nethhostname kernel: Shorewall:FORWARD:REJECT:IN=eth1 OUT=eth1 MAC=aa:bb:cc:dd:ee:ff:gg:hh:ii:jj:kk:ll:mm:nn SRC=188.8.131.52 DST=184.108.40.206 LEN=52 TOS=0x00 PREC=0x00 TTL=127 ID=4862 DF PROTO=TCP SPT=55628 DPT=5938 WINDOW=64240 RES=0x00 SYN URGP=0
DST= always changes for the further log entries…
Thanks for your help.
