NSA 2700 WAN connectivity drops
I just configured new appliances in my enterprise network, we are in 2 locations, first location we have 2 NSA2700 in HA and on the other location we have a TZ370.
On the 2700 we have PPPOE WAN link (1GBPS) and on the 370 its a 100/100 fibre link, both connected throught Site to Site VPN.
The problem that we are experiencing is that it seems that the WAN link on the 2700 is dropping frequently, it affect our ERP connection on the second site. It last only for couple of seconds but enough to be a pain...
I've configured a lot of things (Access rules for VPN zone excluding security services, Bandwidth priority to our VPN connection, etc.) but it's still the same and it makes me crazy,
Anybody can help?
What are the logs telling you about the WAN link? Are you doing logical monitoring through HA / is HA being triggered?
@TKWITS , well HA is not in statefull mode and not triggered at all at the moment, actually it's not a problem with HA.
I don't see any logs on my WAN interface, maybe there is something else I can configure to get more informations?
have you looked at any of the knowledgebase articles?
Check the WAN interface MTU value as per the ISP.
Check the interface duplex mode instead of the Auto Negotiate
Check the connected cable / try to change the cable.
For testing the PPPoE, Configure the PPPoE connection in a Windows machine and check its frequntly dropping or not.
