Webproxy phantomic use of full upload ???

RouterOS General

Hi to evryone.

Im using Mikrotik for ten years and no problem that cannot be solved, but now I have serious and phantomic problems with webproxy.

Im using 6.13 and 5.18 ROS.

After two to six days of activation of transparent proxy on four of my maschines, webproxy started to using all available upload traffic (1Mbps) for no reason. Therefore, it chokes upload and makes latency on download. I tried to change parameters and no difference…

Anybody had similar problems ?

If your device has an IP directly accessible from Internet, you might have been scanned by a bot on port 8080/3128/whatever, and if there is no firewall rule blocking this traffic, your router is probably used for bouncing spam or stuff like that..

thanx.
yes ! it is probable cause !

all 4 maschines are visible from internet.

which port you think should I close from wan interface ?

can you help me with exact rule that will block 8080 and 3128 port from internet if my internet interface is pppoe-out1, and lan interfaces are nat-ed with masquarade rule ?

thanx

try this

/ip firewall filter
add chain=input protocol=tcp dst-port=8080 in-interface=pppoe-out1 action=drop

if your proxy listens on port 8080
