Configure two external IPs whit static NAT in Router to connect with VPN client to an ASA

[pfaiscacisco]

HI,

I'm trying to have access with VPN client to an internal ASA using static NAT in a router 2951, the router has two ISPs directly connected and is connected inside to an ASA.

The router is using the two external IPs mapped to the same ASA internal IP (outside interface), it is possible?

Sometimes I can connect whit booth external IPs, sometimes only work one and no response from the other, and the opposite, have any idea why?

ISP1  \

                ROUTER -- ASA

ISP2  /

Here is the config:

ip nat inside source static udp “ASA-Ouside-IP” 500 “ISP1-IP” 500 extendable

ip nat inside source static udp “ASA-Ouside-IP” 4500 “ISP1-IP” 4500 extendable

ip nat inside source static udp “ASA-Ouside-IP” 500 “ISP2-IP” 500 extendable

ip nat inside source static udp “ASA-Ouside-IP” 4500 “ISP2-IP” 4500 extendable

Thanks

Hi @pfaiscacisco

 How the router's routing table looks like?
