ISP Russian Beeline (ex Corbina), router Netgear WNR-3500L, Tomato Firmware v1.28.9054 MIPSR2-beta K26 USB Ext, here iptables config and nvram dump.
I erased all data in NVRAM, but have strange bug however.
When router up PPTP sometimes at ppp0 interface it have IP 192.168.1.1 (as a router) instead of the external IP (for ex. 18.104.22.168). At this moment cann't to get router control (Web, Telnet, SSH) and Internet doesn't work.
I have this bug when reboot router via Web-interface. Today I have this bug at cold star.
Screenshot of IP adreses from ISP. ISP said that it's router bug, it asks bras for a static IP 192.168.1.1.
Is it really router bug or bras error? Fix it's please if router bug.
