I'm having trouble to set up my first Cisco Router RV345. Everything seems to work well but most of the outgoing port seems blocked. I can access every websites but if i want to reach something with a address like XXX.XXX.XXX.XXX:8080 or www.XXXX.com:88 it doesn't work. I tried several port like 6281 for my Synology, it's like the RV345 blocked every port but the 80, 443, 25, 21. I can't find where to unlock that. I tried to create some access list to allow any to any on port 6281 but still no good. Can somebody help me. Thanks.
Solved! Go to Solution.
is the firewall enabled or disabled (page 63 of the attached guide) ?
it is difficult to comment on what you might be 'missing'. Are the same sites reachable when you don't specify the port ?
Can you give an example ? It might be that the sites themselves don't like to be addressed with specific ports...
What if you disable the firewall ?
Also, make sure you are running the latest firmware release, 1.0.02.16...
It's not about the site. I have several websites i tried. For example, from behind the cisco if i try to reach another external router on a port other than 443 (i change the remote management port to 4430) it won't work. If i change it back to 443, i can reach the router. Or another example, if i try to reach my DVR on an external ip using the port 88 it won't work but work if i change the port of the DVR to 80. I just updated the latest firmware and tried to disable the firewall but nothing change.
