Dropping tcp pkt

Jeg driver et internetgalleri med ca 1.300 aktive brugere. Brugerne uploader billeder til deres galleri. 98% af alle brugere har ingen problemer med at uploade billeder, men enkelte kan ikke uploade billeder. De selvsamme brugere har ikke andre problemer på hjemmesiden, dvs. det er kun upload af filer, som ikke virker.
Jeg har fundet ud af, at routerens firewall giver følgende besked når disse brugere forsøger at uploade:

Dropping tcp pkt 87.11.11.111:53151=>10.10.11.11:80
(ip-adressere er ændret...)

Jeg kan ikke finde ud af, hvorfor firewall'en dropper tcp-pakkerne for netop de få brugere. Er der nogen, som har en ide til, hvad som kan forårsage dette?

Router: Cisco 871
Routeren har følgende software: IOS 12.4(4)T4

Hejsa

Det er CBAC der dropper forbindelsen. Sender du ikke en sh run, for det er noget ip inspect du leder efter.

Som test, bør du fjerne noget af alt det der inspect! Du behøver nok kun:
ip inspect name SDM_HIGH tcp
ip inspect name SDM_HIGH udp
ip inspect name SDM_HIGH ftp

Du bør også fjerne appfw policy-name SDM_HIGH og IPS.

Din router er også lidt overdrevet opsat. Jeg ville nok vælge et lidt simplere opsæt. Du skal passe på at du ikke gør tingene så komplicerede/sikre at du ender med ikke at kunne overskue det og derfor ender med, ubevidst at sænke sikkerhedsniveauet.

Hej Klaus.

Tak for svaret.

Jeg har ikke selv configuret routeren, men har overtaget den og står nu for driften. Så jeg har ikke så meget forstand på det.

Jeg bruger denne application, til at configurere:
Cisco Router and Security Device Manager (SDM)

Kan man bruge den til at lave de ændringer du nævner? Jeg har lidt svært ved at finde hvor. Eller skal jeg bruge kommandoer?

De tæng du nævner, at jeg kan prøve at ændre, kan du kort forklare hvad det er?

På forhånd tak!

Mvh
Peter.

Hej Klaus.

Jeg kiggede på dit forslag og efter at jeg har fjernet IPS så ser det ud til at virke! Tak for hjælpen.

Det er følgende 2 linier i tidligere fremsendte configuration, som er fjernet. Denne linie er væk:

ip ips name sdm_ips_rule

og under afsnittet interface FasteEthernet4 er denne linie fjernet:

ip ips sdm_ips_rule in


Jeg har så følgende tillægsspørgsmål. Er det typisk, at man har IPS slået til? Går man ikke på kompromis, når det ikke er slået til?

Mvh
Peter.
