Missing connectivity after replacing router

[Veridizer]

Hi guys,

Due to flash inconsistency/errors after a power surge issue, my router C800 started acting very strange. Having spent several weeks trying to bring life back into it through formats and the whole lot, I decided to replace it completely. I managed to find the same exact model and proceeded to copy a known good config from the old router (pre-power surge) to the new replacement one.

Almost everything works as it should except for SSH access and NAT rules put in place to allow me to access a VPN server behind the firewall. When comparing the configs side by side, I noticed that the certificate details are missing on the new replacement router. Could this be the reason why I am unable to SSH into the replacement router or access my VPN server behind it?

Hi Georg,

Happy New Year!

Thank you for the cleaned up config. I did a write erase followed by delete vlan.switch and reload then added the config. NAT is now working again to my amazement. Added acl's and confirmed still working.

Thanks for the update. Glad to know that now it is working.

You ask about the pki certificate chain. I notice this in the config

rsakeypair RTR00-rsa

Does this key pair exist? I doubt that the pki self signed certificate is related to issues with the vpn server.

It is interesting that one of the static translations is for a media server. Does access to that media server work?

I will add this when I have access again. I am surprised when you mention nothing should work
It has been working for me this way for well over a year.
