narazil som na problem s cisco1721 ked mi pri spojeni PC-cisco(eth0) rovnym ci krizenym kablom cisco nejak odmieta zapisat si response na jeho arp query, takze sa s nim nedokazem spojit..
Ked som ho dostal do ruk bola v nom nejaka konfiguracia ktoru som nemazal, iba som ju upravil pre moje potreby, niekolko prikazov teda neviem presne co robia, nemyslim vsak ze by to malo na tento problem vplv... Ma s tymto niekto skusenosti? Skusal som dat ...#arp arpa aj ...#arp snap, bezvysledne...

hm, napadlo ma, pripojil si sa do spravneho portu?
lebo vidim ze iba jeden interface mas zivy...
ad2
access-list 1 permit any
hm, mas vsetko zakazane
ak testujes a hladas chybu, logicky vzato, povolim vsetko a odskusam ci to ide, potom to zatvorim a povolujem len co chcem mat povolene...
ono ten config aky je je tam koli tomu ze som to chcel dat ako gateway co neslo, zda sa ze koli tomuto prave, skusim nanovo vsetko spravit, snad to pojde..
e0, fae0 mam proto up line up a ked tam access list nie je tak nema co byt zakazane nie ?
no by si sa cudoval ako ma dokazalo vyzvrtat jedno cisco pix a patral som jak ony... nakoniec pomohlo defacto to co ti navrhol tomase reset do defaults a nanovo
vyskusam zajtra ked bude cas na to, uvidime... 
fakt som cital deny
