3G router - klient - server komunikacija težave

3G router - klient - server komunikacija težave

delux123 ::

Pozdravljeni,

prosil bi nekoga ki se razume na te stvari za razlago. Najprej da vam objasnim nekaj okoliščin. Gre se za klienta ki je sestavljen in network playerja (video decoder, LAN ethernet card, CF kartica,...) kateri prikazuje sliko na LCD zaslonu. Klient se nahaja na terenu in je povezan preko 3G routerja GlobeSurfer II 7.2 (simobilova sim kartica) na internet. Klient komunicira z serverjem preko katerega se tudi krmili (njegov status, upravljanje vsebin in podobno). 3G router ima stalno povezavo - always connected, vendar se včasih zgodi da je status klienta na serverju nedosegljiv, čeprav klient deluje in 3G router ima vzpostavljeno povezavo. Običajno ima vsak klient svoj 3G router. Jaz sem naredil test kjer sem en 3G router povezal preko 8 portnega switcha naprej na 6 enakih klientov. Vsem sem nastavil fiksne IP je (na routerju sem izklopil DHCP). Tudi tukaj se včasih zgodi da nekateri klienti postanejo nedosegljivi, včasih se "poberejo" sami, včasih šele po fizične restartu klienta. Ker to za mene ne pride v upoštev iščem razlog za tako obnašanje. Spodaj dodajam loge iz routerja kjer se vidi komunikacija prek njega. Ker se sam ne znajdem bi prosil če lahko kdo pokomentira, ali se dogaja kaj čudnega kar se nebi smelo, ter kako to preprečiti in podobno.

IP ji klientov so 192.168.1.2/8 ; 192.168.1.10 je bil moj PC preko katerega sem se povezal na router in čekiral loge, 192.168.1.1 je IP routerja, IP serverja je 91.195.147.55 (strežnik za komunikacijo z klienti uporablja porte 8001 8002 8003 18432.

LOG se nahaja napovezavi: http://www.suzuki-klub.com/log.txt

Že v naprej hvala za pomoč, za dodatna vprašanja sem seveda na voljo.

Ali mi res noben ne zna pomagat?

Spodaj je priliman še en security log routerja če mi kdo prosim razloži kaj se dogaja v logu.
