[c-nsp] SMTP Redirection

[a. rahman isnaini r. sutan]

Hallo Jorge,

I did, as the next hop is only ip not with the specific port.
Any destination to smtp will be redirected to 192.168.20.20 which in this 
config should be directly connected to to gateway (router), while in many 
providers their smtp oftenly covered by firewall which might be 3-4 hops 
away from this gateway.
Mail sending is stuck somewhere and I believe the router redirects the 
traffic (let say smtp server directly connected) to the server without 
having any idea to which opened / specific tcp port.

:I have not tried it yet, but I think that you could try something like that
:
: Customers=192.168.10.0/24
: SmtpRelay=192.168.20.20
:
:
: !
: access-list 100 remark SMTP Redirect of Customers to smtp.providername.com
: access-list 100 permit tcp 192.168.10.0 0.0.0.255 any eq smtp
: !
: route-map SMTP-Redirect permit 10
: match ip address 100
:  set ip next-hop 192.168.20.20
: !
: interface FastEthernet 0/0
: description connected to Internet
: ip policy route-map SMTP-Redirect
