Surprised anyone uses these guys after the way they handed the last vuln they had. Neil. Once I moved to Mikrotik, I don't have this issue anymore. The router stays up until I reboot it for a software update.

Re: [uknof] Cisco 887VA - forwarding "kind of breaks" after a week

I run into NAT-related memory issues on pretty much every typical CPE at my house in recent years... Linksys, Netgear, Buffalo. I had to reboot those devices once a week. Once I moved to Mikrotik, I don't have this issue anymore. The router stays up until I reboot it for a software update. Might

Hi Melanie, I am usually using quad 1 or 8, rather than pointing DNS at the router - thats if Im too lazy to run my own in-house resolver. :-) I do have BIND running on a raspberry pi, and it also suffers an inability to do lookups at the same time, which might just be it getting caught up in

Hi Mark, Other than some kind of memory leak chewing everything up, this is in a single person household setting, and Im pretty light on usage really. Will check memory next time it happens, just in case. Tom On Wed, 22 May 2019 at 15:30, Mark Tinka wrote: > Could you be running out of memory

Re: [uknof] Cisco 887VA - forwarding "kind of breaks" after a week

Hi Alistair, I dont think this is a problem with the PPP session dropping. The log doesnt seem to suggest it, and I think there is sufficient chatter in modern web apps to keep a connection alive without the need for persistence. :-) I can add that in, but given it is only happening

Tom, Did you try int Dialer0 dialer persistent This did the trick for my 877 which kept on dropping its PPPoE session. On Wed, 22 May 2019 at 15:26, Mark Tinka wrote: > Could you be running out of memory due to NAT? > > > Mark. > > On 22/May/19 11:02, Tom Storey wrote: > > I forgot to

Hi Tom If you change the IOS version, you should double check it with the bug search tool. For example 16.5 has a bug like Delay in DNS resolve after network flap  . Usually it is either config or firmware related. Have you tried using a different DNS server and not going through the auto

Some kind of memory leak/buffer exhaustion ? "show buffers" could give you some insights. Keith On 5/22/19 4:46 AM, Tom Storey wrote: > Ive noticed that very consistently after about a week (7-8 days), > forwarding partially breaks in some way. Im not sure if it is the Cisco > or something

Re: [uknof] Cisco 887VA - forwarding "kind of breaks" after a week

I was using a 887 a while back and had lots of similar issues. I think the VDSL chipset on its not great on it. I can’t remember if you can use one of the Ethernet points and then use another modem to see if that makes a difference. Cheers, Neil. On 22/05/2019, 09:57, "uknof on behalf of Tom

Hi all, wondering if anyone has come across this and knows how to fix it. I have a Cisco 887VA at home, hooked up to a BT supplied VDSL line (cabinet at end of street), what I believe is called "fibre", but my ISP is Zen. Ive noticed that very consistently after about a week (7-8 days),
