WAN Port Always goes down
WAN Port Always goes down
I lose connection almost 3 to 5 random times a day.
I have two internet connections connected to two wan ports of my ER7206 and the WAn seem to lose connectivity most of the time. I had to reboot the router for internet to both restore connectivity. when this happens I try to connect directly to both my isp routers and seem to be having normal internet connectivity
it's just the er7206 2 wan ports lose connection when I go to their status.
this started happening after I upgraded the firmware 6 months ago. it was running fine with it's stock firmware by the way
hope some one can enlighten me how to fix this

@Clive_A I'm also getting this by the way. Is this a problem and how do I prevent this ?
also is this what you need from me for you to analyze ?
I have set my WAN/LAN1 port (where my computer is connected that has an IP address of 192.168.0.7 also has the omada software controller installed and where wireshark is installed and running as well) to mirror the WAN port where my ISP router/modem is connected.
also below are some more details if it can help
i have changed the subnets of the two ISP modem/routers like you've told me earlier by the way if you can notice

That UDP flood is a problem with your WAN. Someone seems to attack your network and that could be the reason why your WAN is down as it floods the network and the online detection got congested. (For the reason why UDP would affect Online Detection, read the KB about Load Balancing and Online Detection.

@Clive_A is this someone attacking from outside of my private network attacking my isp router or something internally within my network attacking my wan?
any recommendation how I can prevent these attacks?

I am not sure what you have configured but both WANs are on a private network. Not sure if you expose anything on the public Internet. This could be a false alarm as well. You might need to monitor this via Wireshark.

@Clive_A Hi, also wanted to consult you on these screenshots from my wireshark. If you see anything suspicious can you enlighten me please ? I apologize for not being so knowledgeable on this as I am new to this and really appreciate your help.
for reference
192.168.112.4 is the ip address of my er7206 assigned by my main ISP modem connected to my er7206 WAN port
192.168.113.2 is the ip address of my er7206 assigned by my secondary ISP modem connected to my er7206 SFP WAN port
if you need the full log, I can send it. it's 5gb I cn upload it via ftp
