I face an issue at one of the customer site , when the user(10.123.91.0/24) from outside trying to server (10.26.11.32/28) at inside, only one user is able to connect. I wanted to do a NAT overload but router doesnot accept the overload command on an outside NAT.can anybody help on this as increasing size of NAT pool is not an immediate solution as it requires Firewall ruleset change and stuff like that.
ip nat pool test_pool 10.27.255.109 10.27.255.109 netmask 255.255.255.252
ip nat outside source list customer_ACL pool test_pool
ip access-list extended customer_ACL
permit ip 10.123.91.0 0.0.0.255 10.26.11.32 0.0.0.15
thanks & regards
