I have Netgear WNR-3500l router with DD-WRT installed. There is PPTP-server enabled, VPN port forwarded to external network and internet configured with DHCP. Everything works fine but sometimes router hangs - I cannot connect to WiFi and PPTP server (from external network) does not works but client connected to router via Eth still have an Internet access.
Anyone faced that? Is it hardware problem or something in my settings?
