SRX5308 non responsive 2-12 seconds LAN/WAN sporadically through day, drops all VPN connections too
I saw a simlar posting from 6/2015 that was not answered and closed "due to inactivity". I have (5) SRX5308 and they all exibit the same issue. In some cases I have RIP protocol enabled and in others I am using the SRX5308 as a standard firewall with a cable modem uplink. Sporatically and completely random and apparently the higher the firmweare version the more often it happens, the router becomes completely non-responsive for 2-12 seconds, and in most cases VPN connections if any are dropped. Weirdly enough, earlier firmware versions may have had entries in the logs about an exception with register values but newer firmware has absolutely nothing in the logs. I replaced the router with a Cisco 1841 router and the problem goes away compltely but obviously my netgear clients cant VPN in. Does not appear to be volume related either as it happens when the traffic is very low as well as when its averaging 20-30 Mbps. I opened a case with netgear but so far they havent any ideas and suggested it could be a device on the network causing a problem. I agree, its the netgear on the network thats causing the porblem. I like the firewall, especially its VPN thougthput but the constant hang even with its short duration prevents me from keeping this device on the network. Any suggestions? and since I suspect many of you will immediately start asking see the notes below: Currently running firmware: 4.3.4-2, also tried 4.3.3-6, 4.3.3-5, and I beleive an earlier one that came on the router when I bought it. 3 routers have VPN configured between them and one is completely stand alone (the one running RIP is stand alone at anothe location) The 3 with VPN are setup with NAT and the RIP is setup "Classical routing" All are configured for IPv4 only One of the 3 with VPN and NAT has a cable modem on WAN 1 and is configured for failover to DSL on WAN 2, the non-resposiveness still impacts WAN and LAN ports The NAT routers have public WAN IP's and private LAN IP's, the RIP one has public WAN and public LAN ip's. None have DMZ's configured The NAT has firewall rules for specific ports from WAN to LAN, no restrictions on outbound, the RIP router has no rules, all in and out permited, working as a router not a firewall. All have "respond to pings on internet ports" enabled All have "enable stealth mode" None have any blocking enabled (UDP or TCP flood) They all have VPN pasthrough checked None have session limits or throughput/bandwidth limits set None have content filtering enabled None have DHCP server enabled Hope that eliminates most initial questions...
