Nu m-am uitat atent DAR (ma uit mai spre seara) DAR (am mai intrebat):
de ce acoperi/stergi adresele din  subnetul 192.168.0.0/16??
Ele sunt private, nu are cum sa ti le acceseze cineva.

Cîteva observații/întrebări:

1. Prima adresă e 10.0.0.0/8, nu 0.0.0.0/8 că nu vrei să blochezi tot internetul.
2. În afară de adresele din RFC1918 (10.0.0.0/8, 172.16.0.0/12 și 192.168.0.0/16) și multicast: 224.0.0.0-239.255.255.255.255, de ce ai vrea să blochezi altceva?

Cred ca nu intelegi sensul 0.0.0.0/8 (0.0.0.1 - 0.255.255.254) Aici mai multe detalii: RFC6890

si RFC1122


Exista si 10.0.0.0/8 si este trecuta si ea acolo. UPS - am uitat-o.
Pentru restul adreselor, explicatiile aici: https://www.iana.org...-registry.xhtml

Cineva nu și-a băut cafeaua încă și nu-s sigur dacă sunt eu său băieții care au scris RFC1122 și RFC6890

Quote

For
   example, [RFC1122] reserves an IPv4 address block (0.0.0.0/8) to
   represent the local (i.e., "this") network.
După care deschizi frumos RFC1122, dai Ctrl-F dupa 10.0 și nu găsești nimic.

Dar da, am înțeles acum de ce sunt alea rezervate.

sinceritatea este forma cea mai indrazneata a curajului!
FYG: nicio adresa locala din RFC1918 (in cazul tau 192.168.1.0/24 ce face parte din 192.168.0.0/16) dar si restul subnet-urilor ce fac parte din RFC-ul anterior mentionat (10.0.0.0/8, 172.16.0.0/12),  nu trebuie sa fie routate (sa apara in INTERNET).  Ele sunt ip-uri private si pot fi folosite de oricine in reteaua proprie (INTERNET PRIVAT sau mai cunoscut ca LAN).

@demonik: Daca ai RDS poti incerca; o sa observi ca ai minim 2-3 "accesari" mai ales de la ip-uri ce fac parte din subnet-urile definite de RFC1918, accesari ce vin din INTERNET catre interfata WAN a gateway-ului tau.

RFC1918 este folosit si de furnizori pentru jucariile proprii, pana la urma si reteaua furnizorului este tot un LAN. In cazul  tau ogo am impresia ca cineva iti vrea "binele" de tot vezi accesari de la astfel de IP-uri pe interfata WAN. Si cred ca acele IP-uri sunt surse din reteaua lor nu vin din Internet. Cred...

Ce e din 10.0.0.0/8 e din RDS 100% (echipamentele lor folosesc IP-uri din netmask-ul privat pe 8 biti, acest lucru fiind confirmat telefonic). Restul, mai ales 192.168.0.0/16 vin "echipamentele" clientilor RDS, marea lor majoritate setata prost (mai ales la FTTB). Ce vine pe broadcast sunt iarasi echipamente prost setate care fac "discovery" la "n" protocoale ce ruleaza pe diferitele echipamente prezente in retea (ale isp-ului sau nu).
BOGON-urile nu ar trebui sa apara pe WAN dar probleme de genul apar la f multe AS-uri iar unele dintre ele chiar le anunta direct in INTERNET. O lista detaliata AICI.

@demonik
depinde de firewall-ul tau: teoretic tu ai ceva de genul pe chain-ul INPUT: drop all not comming from LAN, si sa pp ca lan-ul tau inseamna 192.168.0.0/24 - Ce crezi ca se intampla cand pe WAN iti vine un BOGON tot din 192.168.0.0/24 - router-ul tau va raspunde sau nu? :)

Sa zicem ca raspunde, chit ca mi se pare imposibil intrucat vine prin interfata ppp care nu-i in LAN (prin LAN ma refer la interface list, care la randul ei contine doar bridge-ul, nu la o clasa de ip-uri, interface list folosit si in regula amintita de tine mai sus), ce se intampla mai departe (daca "raspunde")?

N-am idee, depinde daca este intentionat sau nu, depinde de intentiile "agresorului", depinde de securitate firmware-ului ce ruleaza pe echipamentul respectiv,  dar, ca o concluzie, cred ca e mai usor sa previ decat sa "tratezi".

De fapt problema cu rapunsul este aceiasi chiar daca sursa e un IP privat sau public. In cazul celor private e mai urat deoarece dechide o portita care poate fi o bresa grava de securitate.

abordarea lui ogo este corecta, doar ca - intr-adevar - baga ceva overhead pe router. Insa la nivelul la care a ajung performanta bruta in zilele noastre, zau ca e cam ultima problema de care ma tem. Mai curand am ramas fara pool DHCP decat fara resurse pe masina de rutare. :peacefingers:

Chirurgia endoscopică a hipofizei Chirurgia endoscopică a hipofizei

"Standardul de aur" în chirurgia hipofizară îl reprezintă endoscopia transnazală transsfenoidală.

Echipa NeuroHope este antrenată în unul din cele mai mari centre de chirurgie a hipofizei din Europa, Spitalul Foch din Paris, centrul în care a fost introdus pentru prima dată endoscopul în chirurgia transnazală a hipofizei, de către neurochirurgul francez Guiot. Pe lângă tumorile cu origine hipofizară, prin tehnicile endoscopice transnazale pot fi abordate numeroase alte patologii neurochirurgicale.
