help servizi isa server

[oro18k]

Salve ragazzi e auguri di buone feste!

Allora ho una lan così configurata

Router Cisco Fastweb=>cisco 831=>isa server 2004

ip router Fastweb: 192.168.100.1
ip wan 831 : 192.168.100.2
ip lan 831 : 192.168.200.254
ip isa : 192.168.200.2

Allora prima che montassi l'831 avevo pubblicati i servizi owa ed ecc. di isa e tutto funzionava.. (isa è configurato come Edge Firewall)
Adesso abbiamo montato un 831 ma non riesco ad entrare in isa..praticamente l'831 mi blocca tutto.. ho provato a fare delle prove e ho fatto tutto tramite l'sdm visto che so pochissimo di cli

vi posto la configurazione dell'831 perchè magari potrebbe essere un problema di isa che deve essere configurato in back firewall, ma intanto volevo sapere se la configurazione dell'831 è corretta essendo la mia prima volta che ci metto mano!

up raga pls

Dovresti spiegare la lan come' strutturata un pò meglio, gli host che devono accedere al server si trovano sulla 100.x immagino? Il router lo utilizzi per le instradare fra le 2 subnet? Una spiegazione dettagliata su chi deve accedere come e perchè è vitale dato il port forward su nat e le access list che hai.

grazie per la risposta!

allora isa server ha ip 192.168.200.2
e l'831 ha ip 192.168.200.254
e la wan 831 192.168.100.2


allora ho un sbs2003 con isa server 2004 installato in ufficio

e i pc hanno ip 192.168.23.x

cioè io vorrei che mi ripondesse isa server,quindi all'ip 192.168.200.2, per accedere ai vari servizi web..

ma praticamente leggendo i log dell'831 mi dice che sta bloccando l'accesso

non so se mi sono spiegato bene... magari fammi te delle domande + approfondite

fai conto che prima di mettere l'831 i servizi isa funzionavano normalmente

cmq a monte di tutto ce sta un router cisco di fastweb (192.168.100.1) dove ho indirizzato tutto il traffico alla wan dell'831 (192.168.100.2)

grazie mille, ciao!

[Rickert]

in poche parole sono i tuoi host che devono comunicare col server no? dato che sono sotto la 23 a quale router si appoggiano per essere indirizzati sul server che sta sotto la 200? insomma che gateway hai impostato sui pc?
