After 2-3 days the forwarding statement "ip nat inside source static tcp 192.168.1.250 80 x.x.x.x 80 extendable " dissapears from the running confing, but the forwarding is working. After the reset the forwarding is missing. Anybody knows what bug i`m hitting. Thanks.
Sometimes the most simple reason is the most probable... You said that after the reset, the "forwarding is missing" - I take it that after reloading the device, the offending ip nat inside source static command is not present in the running-config and hence the static port forwarding does not work. That would in turn mean that this command is not present in the stored startup-config file because otherwise, it would be loaded during the device bootup.
Is it absolutely certain that this command is present in the startup-config? Also, is it absolutely certain that there is no one modifying the running-config - via CLI, SNMP, ...?
Yes i think this is happening. The ip nat inside static command dissapears from running config , when after configuring some other things from the CLI i issued the wr command the running replaces the startup and at the reboot the forwarding is not there. Nobody have the access but me on the router. When after some time i look at the config the line is gone but when i issue sh ip nat translations it shows the static mapping and everything is working,except the line in the running config. Strange
