Hi fellow sysadmins! :-)
At the moment I'm running an OpenVPN server on a non standard port. Unfortunately this make some roadwarriors unable to connect because of traffic limitations depending on where they are. Sometimes they only have 53,80,443 open or there is traffic shapping applied to all ports besides there ones.
What do you normally use to avoid these issues?
I have a cisco running IOS 12.0(25) responding to two different IPs addresses: IP_A and IP_B. Behind this router I also have two different servers: server_A and server_B.
What I want is to forward port 22 to both servers, so:
IP_A, port22 -> server_A, port22
IP_B, port22 -> server_B, port22
ATM this only works for one of them (server_A), this is my config:
interface Ethernet0/0
description Internet
ip address IP_A 255.255.255.0
ip address IP_B 255.255.255.0 secondary
no ip directed-broadcast
ip nat outside
no ip mroute-cache
no cdp enable
ip nat pool pool_A IP_A IP_A netmask 255.255.255.0
ip nat pool pool_B IP_B IP_B netmask 255.255.255.0
ip nat inside source list A pool pool_A overload
ip nat inside source list B pool pool_B overload
ip nat inside source static tcp server_B 22 IP_B 22 extendable
ip nat inside source static tcp server_A 22 IP_A 22 extendable
access-list A permit server_A
access-list B permit server_B
Is there any way of a cisco router acting as a dhcp server to record the leases of its clients to a syslog server?
I'm currently using the DHCP server database agent feature to record the leases to a file through a ftp server.
I'm configuring a Cisco 3640 and it's not saving simple things like my hostname.
I've tried with 'wr' and 'copy running-config startup-config'. Also erased the configuration but no luck.
There's no error whatsoever when running the above commands.
Is my flash bad?
Anyway I can debug this more thoroughly?
Thanks!
